Title: Cross lapping apparatus

Abstract: A high speed cross-lapping apparatus is disclosed which forms batting from a high total denier tow of continuous filament material such as polyester. The apparatus includes a reciprocating carriage having a pair of steel rolls which deliver the tow to an underlying receiving conveyor. To drive the carriage, either a unidirectionally driven belt or a reversible electric motor may be provided. Inertia reversal apparatus including a pneumatic cylinder is located at each end of the carriage stroke. To accomodate differences in tow length as the carriage reciprocates, a horizontally disposed length compensating assembly is employed.
