Abstract

A method of making pile material comprising pile strands or the like arranged in side-by-side relation, and a backing member bonded to the strands, the method comprising the steps of providing a bundle of pile strands, the strands extending in side-by-side relation and being held in pressurized engagement with each other by a wrapper surrounding the strands, cutting the bundle including the wrapper into slices, and positioning each slice in a form having a wall surrounding the slice and spaced outwardly thereof. The wrapper is removed from the slice, thereby allowing the pile strands to expand laterally outwardly into engagement with the wall of the form for being held by the form. A backing member is thereafter bonded to the pile strands on one face of the slice.

Dependent claims

A method of making pile material comprising pile strands or the like arranged in side-by-side relation, and a backing member bonded to the strands, said method comprising the steps of:

(a) providing a bundle of pile strands, the strands extending in side-by-side relation and being held in pressurized engagement with each other by a wrapper surrounding the strands;
(b) cutting the bundle including the the wrapper into slices, each slice having a portion of the wrapper thereon;
(c) positioning each slice with the said portion of the wrapper thereon in a form having a wall surrounding the slice, the form being of generally the same sectional shape as the slice but of slightly larger sectional area than the slice for providing a space between the periphery of the slice and the wall of the form;
(d) removing the said portion of the wrapper from the slice, thereby allowing the pile strands to expand laterally outwardly into engagement with the wall of the form, the form thus serving to hold the pile strands;
and
(e) bonding a backing member to the pile strands on one face of the slice.
