Including Mechanical Means To Apply Force To Stretching Tool Patents (Class 227/13)
  • Patent number: 8205311
    Abstract: An apparatus and process for causing excess covering material at a workpiece corner to be gathered, folded and secured to a back side of the panel. A corner tucking apparatus includes a gathering plate positioned adjacent a positioning structure, and moves inwardly across the back side of the workpiece, from the corner, to gather and fold the corner flap. The gathering plate has a generally V-shaped notch which causes excess material to be gathered together as the plate moves inwardly. The gathered material upon reaching the apex of the notch is folded downwardly into contact with the back side of the workpiece. A securing structure which is carried inwardly with the gathering plate is then activated to fixedly secure the folded flap to the pad or workpiece.

  • Patent number: 4349142
    Abstract: A high speed, portable, rug binding machine in the form of an electric-powered hand-tool carrying and dispensing a roll of binding tape has floor-engaging canted wheels for directing the frame of the machine into a rug as it is rolled along a rug edge to which a binding is stapled by the machine as the operator pulls a trigger causing a solenoid to drive the stapler by way of a power linkage which automatically adjusts for rug and for binding thickness; the machine has adjustment for varying rug-to-binding holding force, prior to stapling, and rug introduction angle; simplicity of mechanism provides compactness and light weight suitable for one-hand manipulation by the operator under all conditions.
