Title:
PATTERNED COMPOSITE MATERIAL
United States Patent 3728203
Abstract:
A patterned composite material comprising a flexible sheet material adapted to be gathered in at least one direction with at least three rectangularly shaped elastic strip members individually applied to the sheet material in a stretched secured condition so that the sheet material connects the strip members. The strip members are so arranged on the sheet material that two strip members are positioned in line and spaced apart to form a space therebetween, with at least one strip member being positioned in a spaced distance to the side of the center axis of said two in line strip members. The elastic strip members are constructed to return to substantially their original dimensions after being stretched to carry the sheet material into a gathered configuration so that the plurality of elastic strip members forms a gathered composite pattern on the sheet material with the areas of the sheet material opposite the elastic strip members being gathered by the constrictive action of the plurality of elastic members and the adjacent areas to the elastic member secured areas being slightly depressed in relation to the plane of the areas opposite the elastic members.

Description:
The present invention generally relates to a patterned composite material and more specifically to a novel and improved sculptured material and to the process for making it. The sculptured material of the invention has an unusual decorative pattern through a novel process which causes the material to take on an attractive gathered look. The novel process converts the surface of the material from a standard relatively planar surface to an irregular undulating, alternately raised and lowered surface, creating an attractive and unique appearance. The above-mentioned material is especially conducive to the manufacture of purses, in that the economical, decorative material is easily applied to the purse body to provide a handsome, contoured appearance.
Other features and advantages of the invention will be apparent from the following description of the embodiments of the invention as shown in the accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENT
As shown in FIG. 1, a piece of base material 10 of a vinyl composition is used, although plastic materials or fabrics of a natural or synthetic composition can be substituted. While the base material 10, as shown, is of a single layer, it should be noted that the material can be a composite of several different layers of material comprising any desired combination. However, the base material used is preferably relatively unstretchable. The base material 10 is preferably carried by a base or a supply roller, not shown, and is removed from the roller and placed on a processing area. An elastic web from a separate supply roller is preferably cut into a plurality of elastic members 12 having an approximately two-inch square configuration. The elastic web can be made of any elastic material provided the elastic material has sufficient elasticity to return to its original configuration after the elongating stresses are relieved.
The advantage of using a plurality of separate elastic members 12 of small size with the base material 10 is that a tougher composite material 20 is created with the elimination of "puffing" which occurs when a large elastic web is used.
The square elastic members are then stretched approximately 1 inch, or to a set desired distance, depending upon the elasticity of the elastic material used and the nature of the base material 10. Adhesive is then applied to the elastic members. The elastic members are secured to the back of the base material 10 at spaced apart intervals of approximately 1 inch. The elastic members can be overlapped or preferably positioned adjacent each other in staggered relation such as that shown in FIG. 3.
In the preferred embodiment, each of the elastic members is preferably stretched in substantially one direction. The stretched elastic members 12 are designated by the numeral 14. The pattern of the composite material 20 can be changed depending on whether the constrictive reaction of the elastic members 12 is in a lengthwise or crosswise direction or a combination of both. Additional pattern changes can be provided by the substitution of different geometric shapes and spacings of the elastic members.
When the stretched elastic members 12, secured to the base material 10, return to their relaxed or normal configuration, the adhesively secured base material 10 is caused by the constrictive reaction of the elastic members 12 to gather and assume the corresponding position of the relaxed elastic members, as shown in FIG. 3. After the elastic members 12 have relaxed, the front of the finished composite inventive material 20 takes on a decorative patterned or contoured look, as shown in FIG. 4.
As shown in FIG. 4, the gathered areas 16 of the base material form a wrinkled, ridge-like appearance, while the adjacent areas 18, which are not secured to the elastic members, take on a depressed configuration having a somewhat smoother appearance.
Alternatively, adhesive can be applied to the back of the material and the elastic members placed thereon. The adhesive applied to the elastic members 12 can be placed on the members in the stretched or unstretched position. The adhesive can be directly applied by a conventional spreading device or sprayed on, depending on the particular type of adhesive apparatus used, or can be predeposited on the elastic web.
The gathered composite material 20 is then run through a rubber fast-roller press, or other suitable pressing means, under pressure so that a permanency in the adhesion of the bond between the elastic members 12 and the base material 10 is achieved, while, in addition, simultaneously crinkling or wrinkling the gathered material into substantially permanent patterns. The patterned composite material 20 is then cut into pieces of various configurations. The cut pieces are placed onto the skeleton or body of a purse or other suitable item and are sewn or glued to the skeleton or body to form the item desired, as, for example, the purse 22 shown in FIG. 5. The process is preferably done in small-lot approach, because it is easier to do pieces for the right size of the picket book or other small sized items.
While the preferred embodiment of the invention has been disclosed, it is understood that the invention is not limited to such an embodiment since it may be otherwise embodied in the scope of the appended claims.
Other features and advantages of the invention will be apparent from the following description of the embodiments of the invention as shown in the accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENT
As shown in FIG. 1, a piece of base material 10 of a vinyl composition is used, although plastic materials or fabrics of a natural or synthetic composition can be substituted. While the base material 10, as shown, is of a single layer, it should be noted that the material can be a composite of several different layers of material comprising any desired combination. However, the base material used is preferably relatively unstretchable. The base material 10 is preferably carried by a base or a supply roller, not shown, and is removed from the roller and placed on a processing area. An elastic web from a separate supply roller is preferably cut into a plurality of elastic members 12 having an approximately two-inch square configuration. The elastic web can be made of any elastic material provided the elastic material has sufficient elasticity to return to its original configuration after the elongating stresses are relieved.
The advantage of using a plurality of separate elastic members 12 of small size with the base material 10 is that a tougher composite material 20 is created with the elimination of "puffing" which occurs when a large elastic web is used.
The square elastic members are then stretched approximately 1 inch, or to a set desired distance, depending upon the elasticity of the elastic material used and the nature of the base material 10. Adhesive is then applied to the elastic members. The elastic members are secured to the back of the base material 10 at spaced apart intervals of approximately 1 inch. The elastic members can be overlapped or preferably positioned adjacent each other in staggered relation such as that shown in FIG. 3.
In the preferred embodiment, each of the elastic members is preferably stretched in substantially one direction. The stretched elastic members 12 are designated by the numeral 14. The pattern of the composite material 20 can be changed depending on whether the constrictive reaction of the elastic members 12 is in a lengthwise or crosswise direction or a combination of both. Additional pattern changes can be provided by the substitution of different geometric shapes and spacings of the elastic members.
When the stretched elastic members 12, secured to the base material 10, return to their relaxed or normal configuration, the adhesively secured base material 10 is caused by the constrictive reaction of the elastic members 12 to gather and assume the corresponding position of the relaxed elastic members, as shown in FIG. 3. After the elastic members 12 have relaxed, the front of the finished composite inventive material 20 takes on a decorative patterned or contoured look, as shown in FIG. 4.
As shown in FIG. 4, the gathered areas 16 of the base material form a wrinkled, ridge-like appearance, while the adjacent areas 18, which are not secured to the elastic members, take on a depressed configuration having a somewhat smoother appearance.
Alternatively, adhesive can be applied to the back of the material and the elastic members placed thereon. The adhesive applied to the elastic members 12 can be placed on the members in the stretched or unstretched position. The adhesive can be directly applied by a conventional spreading device or sprayed on, depending on the particular type of adhesive apparatus used, or can be predeposited on the elastic web.
The gathered composite material 20 is then run through a rubber fast-roller press, or other suitable pressing means, under pressure so that a permanency in the adhesion of the bond between the elastic members 12 and the base material 10 is achieved, while, in addition, simultaneously crinkling or wrinkling the gathered material into substantially permanent patterns. The patterned composite material 20 is then cut into pieces of various configurations. The cut pieces are placed onto the skeleton or body of a purse or other suitable item and are sewn or glued to the skeleton or body to form the item desired, as, for example, the purse 22 shown in FIG. 5. The process is preferably done in small-lot approach, because it is easier to do pieces for the right size of the picket book or other small sized items.
While the preferred embodiment of the invention has been disclosed, it is understood that the invention is not limited to such an embodiment since it may be otherwise embodied in the scope of the appended claims.
