  • Patent number: 6176002
    Abstract: The method of installing a handle in a mattress border comprising the step of bending a back strap and a material into a U shape so that inside surface is convex outward and so that first apertures are aligned, inserting a pulling tool through the aligned apertures, coupling a second coupling means to a first coupling means, and using the tool to pull the handle so that one of anchors passes through the first aligned apertures.

  • Patent number: 6170143
    Abstract: A handle for a mattress border is anchored with spaced grommets in the border against which anchors on the handle ends may bear. The anchors are designed to allow a leading end of the handle to be drawn through grommet opening. A back strap between the grommet openings is shaped to allow clamping to move the grommet opening to aligned position. To allow the drawing of the anchors through the grommet opening, at least one of the anchors is provided with first couplings. A puller rod is designed to be inserted through at least one of the grommet openings. The puller rod is provided with second couplings, designed to cooperate with the first couplings to achieve the pulling function.

  • Patent number: 5740713
    Abstract: A notch cutter provides a first pair of inwardly facing shear edges in a V. A second pair of outwardly facing shear edges make an almost complementary V with a slightly smaller convergence angle. One pair of shear edges is caused to contact respective ones of the other pair along contact points moving from the entrance of the notch to the apex of the notch. One pair of shear edges is resiliently mounted relative to the other. When used to separate strips and form the ends of the separated strips, the V's of the first and second edge pairs may be truncated since the shear edges need only be wider than the strips on which they act to form their separating and edge shaping functions.

  • Patent number: 5652984
    Abstract: A handle for a mattress border is anchored with spaced grommets in the border against which anchors on the handle ends may bear. The anchors are designed to allow the handle to be drawn through the grommet openings when the latter are aligned. A back strap between the grommet openings is shaped to allow clamping to move the grommet openings to aligned position.

  • Patent number: 5463920
    Abstract: A fabric notch cutter includes a pair of inwardly facing shear edges which converge to a first apex and a pair of outwardly facing shear edges which converge to a second apex at a slightly lesser angle than the convergence angle of the inwardly facing shear edges. Each of the outwardly facing shear edges contacts a respective one of the inwardly facing shear edges at a contact point. Further, the outwardly facing shear edges are resiliently mounted such that they are retracted toward their support member during a cutting operation. The points of contact between the shear edges progress toward the apices during the cutting operation.

  • Patent number: 5426838
    Abstract: A vent applicator positions, a skirted vent blank on one side of a fabric and a die on the other, and impels the blank downwardly through the fabric so that the skirt is curled up and out by the die to clamp the fabric to the blank. To position the vent blank, it is suspended on deflectable fingers which are deflected when the blank is impelled downwardly. Preferably a hole is punched in the fabric before the die is moved downwardly. Sensors detect the presence of a vent blank ready for downward movement. A washer may be positioned over the die for clamping between the upturned skirt and the fabric. If a washer is used sensors detect the presence and positioning of a washer.
