Double-tiered swirling machine for pile fabric

摘要

A device for forming surface designs on pile fabric is disclosed, in which a plurality of conical brushes are utilized to swirl the fibers of the fabric. The device is provided with two tiers of rotatable brushes, and the fabric passes beneath both tiers of brushes. The brushes of one tier constantly rotate in contact with the surface of the fabric, while the brushes of the other tier also rotate, but are normally suspended above the fabric. Control means is provided to selectively move individual brushes in the second tier downward, and into momentary contact with the pile fabric passing beneath. Shifting means are provided to selectively move both tiers of brushes as a unit across the width of the fabric.
