ABSTRACT:
Dye is applied to the lower surface of a dye pickup roll for transfer to the pile surface of a length of carpet, and a squeegee roll engages the dye pickup roll after the dye has been applied to the pickup roll and before the dye is transferred from the pickup roll to the carpet. The external surface of the squeegee roll is approximately cylindrical with a multiple number of depressions formed therein, and the squeegee roll can be rotated and reciprocated with respect to the dye pickup roll, so that its high spots tend to wipe or "squeegee" the liquid dye from the surface of the dye pickup roll and its depressions or low spots tend to permit the dye to pass beyond the squeegee roll on the pickup roll in a pattern and move with the pickup roll into contact with the pile surface of the carpet. When the squeegee roll is reciprocated, it tends to prevent the pattern from being repeated on the dye pickup roll and on the carpet. When the squeegee roll is not reciprocated or when it is reciprocated in timed relationship with respect to its rotation, a repeat design can be applied to the carpet.
