Stripping Foam Carpet Tile

摘要

Foam backed carpet tiles are removed from a supporting floor surface without leaving a residue of foam by providing a flexible thin polyester sheet material with a first adhesive material bonding the bottom surface of the foam layer to the top surface of the sheet material and a second adhesive between the bottom surface of the sheet material and the supporting floor surface. The sheet material is caused to separate from the supporting floor surface when removing the carpet tile by the pulling force being applied also to the polyester sheet which has low stretch less than the carpet itself. Also the first adhesive material provides a greater bond strength between the sheet material and the second layer than a bond strength of the second adhesive material and by causing the structural integrity of the second layer to be greater than the bond strength of the second adhesive material.

1. A method of attaching carpet tiles to and subsequently removing the carpet tiles from a supporting floor surface comprising:
providing a carpet material having a first layer of primary carpet fabric having a plurality of pile forming yarns projecting outwardly therefrom and a second layer of a foamed polymer cushioning material disposed on a side of the first layer opposite the pile forming yarns so as to define a bottom surface of the second layer for application to a supporting floor surface; the first and second layers being coextensive with overlying side edges along edges of the strip; providing a flexible sheet material having a top surface and a bottom surface; applying a first adhesive material between the bottom surface of the second layer and the top surface of the sheet material so as to bond the sheet material to the bottom surface of the second layer; attaching the bottom surface of the sheet material to the supporting floor surface by a second adhesive therebetween; and removing the tile from the supporting floor surface by pulling the tile while the sheet material and the attachment of the sheet material to the bottom surface of the second layer prevents any part of the second layer from remaining attached to the supporting floor surface.
