ABSTRACT:
A double sided pile fabric is formed by a reciprocating needle in cooperation with latchless loppers on opposite sides of the base fabric, the reciprocating needle guiding the yarn through the base fabric to form loops on opposite sides thereof. The latchless lopper on one side retains alternate loops in the path of the needle so that the adjacent loops are formed inside the alternate loops after which the alternate loops are pulled taut about the adjacent loops.
