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.
