Abstract
Method and apparatus for automatically carrying out a toe-closing operation for a plurality of seamless hose simultaneously by several successive operational steps. One cycle of the successive steps being carried out during one cycle of the travelling of said hose along an endless passage. The steps are: sucking the toe portion of the hose into a suction tube, holding the welt portion inside out on finger pieces, clamping the toe portion of the hose by the clamp of the sewing machine after the toe closing operation has been enlarged laterally and moved forwardly, and sucking the toe closed hose into the suction tube by the suction force in the suction tube.

A method for automatically closing the toe of seamless hose, by means of four or more pairs of holding units, each having a suction tube and finger pieces and arranged parallel and horizontally which firstly travel at a low speed along the endless passage, and then at a higher speed in the region near the toe-closing position, so that one cycle of the toe-closing is accomplished during one cycle of the traveling of said hose along said endless passage, said method comprising:
- sucking the toe portion of the hose into a suction tube provided with the finger pieces;
- spreading and holding the welt portion of the hose sucked into the suction tube in an inside-out manner over the finger pieces, so that the toe portion of the hose is projected beyond the forward end of the finger pieces;
- laterally spreading the projecting toe portion into a flat shape and carrying forward the toe portion on the finger pieces;
- clamping with a clamp of a sewing machine the flattened toe portion of the hose;
- sewing the toe portion closed;
- and
- sucking the toe-closed hose into the suction tube by the suction force in the suction tube, after releasing said toe-closed portion of the hose from the clamp of the sewing machine.
A method of automatically closing the toe of seamless hose comprising the steps of
- sucking a toe portion of a hose into a suction tube of a holding unit having finger pieces mounted adjacent the suction tube;
- placing a welt portion of the hose over the suction tube and finger pieces;
- thereafter moving the finger pieces laterally of the suction tube and outwardly of the suction tube to flatten the toe portion and carry the toe portion forward of the suction tube;
- clamping the toe portion within a sewing machine and sewing the toe portion closed;
- and
- thereafter sucking the closed toe portion into the suction tube to draw the hose into and through the suction tube.
A method of automatically closing the toe of seamless hose comprising the steps of
- sucking a toe portion of a hose into a suction tube of a holding unit having finger pieces mounted adjacent the suction tube;
- spreading a welt portion of the hose over the suction tube and finger pieces while pulling the toe portion out of the suction tube and over the suction tube and finger pieces;
- thereafter moving the finger pieces relative to the suction tube to flatten the toe portion while carrying the toe portion forward of the suction tube;
- then clamping the toe portion within a sewing machine;
- retracting the finger pieces from the clamped toe portion;
- sewing the clamped toe portion closed;
- and
- thereafter sucking the closed toe portion into the suction tube to draw the hose into and through the suction tube.
