ABSTRACT:
A carriage assembly for automatic face up one way spreading of multiple plys of fabric or any other web-like material of a predetermined length, which is automated to operate in a continuous manner in the absence of operator manipulation at the termination of each fabric spreading cycle. The device incorporates a fabric or web-cutting assembly normally enclosing a transversely traveling severing blade and means for automatically engaging the free end of the fabric after sequenced severing so as to maintain the fabric in a fixed relation relative to the assembly during return or non-spreading carriage motion thereby preventing disturbance or change of position of the free end of the fabric as caused by carriage motion airflow, so that upon automatic recommencement of spreading, the end of the fabric will be deposited at a predetermined position on the spreading surface which will be accurately repeated for each subsequent automatically deposited ply of fabric, thereby providing maximum fabric utilization.
