Abstract
Methods, systems and devices to divide a layer of a first material from another material, to which is attached, are provided. Particularly, for the separation of the PVC from a modular carpet. By the use of a parallel blades mechanism that through an opposite counterpart apply at least a shear stress over the material of the modular carpet to tear the PVC layer and divide it. The carpet is preheated to facilitate the process of division and reuse of said PVC.

A method for dividing a layer of a first material from a layer of a second material in a composite piece, the method comprising:
- preheating the composite piece;
- placing the composite piece between a counterpart and a pair of blades with the layer of the second material facing said counterpart, wherein said blades are movable along a cutting axis by a predetermined travel distance, and wherein the counterpart, which is fixed respective to the blades is located over the cutting axis in a parallel relation with the blades and wherein said counterpart is able to be located between and separately from said blades when said blades move along the cutting axis toward said counterpart, and wherein the composite piece is disposed over the cutting axis at a distance substantially equal to half a length of said composite piece, thus defining two equal sides of composite piece;
- dividing, utilizing the counterpart and the pair of blades, the layer of the first material from the layer of the second material by applying a double shear stress over the composite piece while the blades move toward the counterpart until the blades have moved a travel distance that is approximately larger than half the length of the composite piece, wherein the double shear stress includes stress applied by the blades and stress applied by the counterpart.
A system for dividing a layer of a first material from a layer of a second material in a composite piece in combination with a device for dividing a composite piece, the system comprising:
- a device for dividing comprising:
- a counterpart and a pair of blades, said blades are movable along a cutting axis by a predetermined travel distance, wherein the counterpart that is fixed respective to the blades is located over the cutting axis in a parallel relation with the blades and wherein said counterpart is able to be located between and separately from said blades when said blades move along the cutting axis toward said counterpart;
- and
- wherein the composite piece is disposed over the cutting axis between the counterpart and the pair of blades with the layer of the second material facing said counterpart at a distance substantially equal to half a length of said composite piece, thus defining two equal sides of composite piece;
- and
- wherein the device for dividing divides the layer of the first material from the layer second material by applying a double shear stress over the composite piece while the blades move toward the counterpart until the blades have moved a travel distance that is approximately equal to half the length of the composite piece, wherein the double shear stress includes stress applied by the blades and stress applied by the counterpart.
