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.
