Abstract: A folding table for use in forming a third fold in a printed product, is provided with a plurality of detents that can be shifted into and out of the movement path of the product. Any accumulated paper remnants can be removed from the folding table when the detents, or selected ones of the detents are moved out of the product path. The method of operation of the device facilitates the elimination of production interruptions.

Abstract: Disclosed is a reciprocating pneumatic tool that includes a retainer mechanism for preventing the piston from freely exiting the barrel of the tool when the retaining sleeve and workpiece are removed. The retainer mechanism does not interfere with the functional operation of the tool when the workpiece and sleeve are attached to the tool. The retainer mechanism is mounted distally around the butt of the workpiece such that no contact occurs with the retainer mechanism or the piston.

Abstract: A mechanical driver is provided including a gun-shaped housing having a horizontal upper extent and a vertical lower extent integrally coupled to the upper extent and extending downwardly therefrom. The upper extent has a nozzle. A spring biased actuator rod is slidably situated within the nozzle of the upper extent of the housing. A spring assembly is included for biasing the actuator rod forwardly. A trigger assembly is provided including a trigger hingably coupled to the lower extent of the housing. The trigger is adapted to swivel between an unbiased vertical orientation and a biased rear tilted orientation, whereby the trigger is adapted to bias the actuator rod rearward and further release the same such that the actuator rod drives forwardly within the nozzle.

Abstract: A method is disclosed for forming a filter cartridge which includes the steps of providing a cylindrical filter element having a plurality of radially extending longitudinal pleats, engaging an outer periphery of the cylindrical filter element along a substantial portion of the length thereof, and simultaneously moving the plurality of radially extending longitudinal pleats into a laid-over spiraled configuration along the entire length of the cylindrical filter element to form a spiral pleated filter element. An apparatus is also disclosed for effectuating the disclosed method.

Abstract: A new tool with interchangeable heads for the selection of a proper tool for the digging or manipulating of a surface for landscaping or construction purposes. The inventive device includes a shaft and interchangeable head members insertable into the shaft including a first head member with an auger head section extending from a rod section, a second head member with an mallet head section extending from a rod section, and a third head member with a chisel head section extending from a rod section.
