ABSTRACT:
Lengths of material are collected in side-by-side relation in a group and delivered as a group to a receiving station by an apparatus which includes a support table constituted by a number of spaced parallel arms pivoted coaxially with each other about one end. Each arm has a finger which projects upward above the arm and which can be moved toward the pivot for moving the lengths laterally of themselves towards a stop adjacent the pivoted ends of the arms, and during this movement the arms are inclined downward towards their pivot at such an angle that the fingers need exert only a small force to move the lengths towards the stop. A mechanism is provided for moving lengths of material individually or collectively on to the support table for movement by the fingers towards the stop, and a device spaced from the pivots emits a signal when the combined width of the lengths of material which have been moved towards the stop by the fingers reaches a predetermined value, and this signal initiates operation of a mechanism for moving the group of lengths having the predetermined width past the stop to the receiving station.
