Abstract: A multi-stroke air cylinder providing a precisely directed and controlled stroke in the face of lateral, torsional and tilting loads on a tooling plate. The multi-stroke cylinder utilizes a plurality of mechanically linked pneumatic or hydraulic pistons having different stroke lengths that can be added together in any combination, allowing the user to select any stroke length up to a predetermined, total combined stroke length, in increments equal to the stroke length of the smallest cylinder. The multi-stroke cylinder includes a head assembly having a fluid inlet for introducing fluid to the cylinder at a first pressure. The cylinder also includes a first positioning system having a plurality of pistons capable of moving a piston rod away from the first positioning system, and a second positioning system located between the head assembly and the first positioning system.

Abstract: A tensioned mounting device is disclosed. The device is designed to apply a gentle tensioning force along the attached edges of a mounted thin, planar device, such as a poster. The device is comprised of two variable-length bar mechanisms. Each mechanism includes at least two frames slidably joined by a connector bar. A tensioning device, such as a spring, exerts an outward force between a frame and the connector bar.

Abstract: A system of manufacturing shirt front assemblies is disclosed wherein a connected series of center plait pattern parts and a series of shirt front pattern parts are fed simultaneously to a sewing machine and sewn together to form a connected series of shirt front assemblies. The connected series of shirt front assemblies are conveyed away from the sewing station through a buffering system to a cutting station where the center plait pattern parts are cut apart and trimmed so as to have their ends coextensive with the edges of the shirt front pattern parts, and the cut-apart series of shirt front assemblies are stacked.
