Abstract
A method of making pile fabrics in which a compacted block of strands of pile forming material is incrementally discharged from an open end of a container in successive increments of an amount equal to the desired length of pile and, following each discharge of the block from the container, a pile slice is severed from the block while being deposited directly onto and secured to an advancing layer of adhesive carried by a release surface to form a pile fabric of cut pile tufts secured to an adhesive substrate which is then removed from the release surface.
Claims11
A method of making pile fabrics, such as carpets, rugs and the like, which comprises providing a pile strand block of substantially parallel strands of pile forming material in an open-ended container, incrementally feeding from the container the pile strand block parallel to the axes of the pile strands in successive increments of an amount equal to the desired length of pile, forming a substrate by depositing a layer of adhesive onto a release surface, severing each successive fed increment of pile strands transversely of the pile strand axes to form a pile slice while bringing the severed pile slice into contact with the layer of adhesive for securement thereto and to form cut pile tufts thereon, and then separating from the release surface the substrate with the cut pile tufts thereon.
A method of making pile fabrics, such as carpets, rugs and the like, which comprises providing a pile strand block of rows of substantially parallel strands of pile forming material in an open-ended container, incrementally feeding from the container the pile strand block parallel to the axes of the pile strands in successive increments of an amount equal to the desired length of pile, forming an adhesive substrate by depositing a layer of adhesive onto a release surface, progressively severing the pile strands of each successive fed increment of the pile strand block transversely of the axes of the pile strands to form a respective pile slice thereof while progressively depositing the severed pile strands onto the previously formed adhesive substrate for securement thereto and to form rows of cut pile tufts thereon, while advancing the release surface with the substrate thereon relative to the block of pile strands, then curing the adhesive substrate on the release surface, and peeling the substrate away from the release surface to form the pile fabric.
