Abstract: A high speed vertical textile lapper has a comb reciprocated by a first motor and a presser bar reciprocated by a second motor, both motors being under a common servo motor control. The linear comb is reciprocated by a comb crankshaft in a crankcase while the presser bar is reciprocated by a bar crankshaft in order to deposit a lapped web onto a horizontal conveyor which sends the web through an oven where some of the web fibers fuse to adhere the finished web. The incoming web to be plated is carried to the lapping zone by a combination of horizontal and vertical conveyors. These feed the descending web close to the lapping zone. The comb crankcase has pressurized lubrication and external cooling. The servo control permits PLC synchronization.

Abstract: A textile lapping machine has an inclined reciprocating comb which deposits a vertically descending fibrous web onto a mesh belt of an endless conveyor which travels through an oven. A reciprocating presser bar pushes the pleats formed by the comb into a shark unit which extends across the width of the mesh belt. The unit has a toothed plate which initially slows the pleated web and longitudinal fingers which overlie the conveyor and form a shallow lapping zone. A textile card delivers the fibrous web to the lapping zone and the oven fuses any low melt synthetic fibers in the web to the surrounding fibers to give a batt with a density of 80-2000 gsm. The comb path direction remains constant and the presser bar and shark unit are moved towards and away from the comb. The drives to the comb and presser bar are independent.
