Claims
- 1. A method of closing the toe end of a hose blank which terminates in a bead or barrier on a toe closing machine on which the toe end of the hose blank is transported past a seamer which generates a closing seam therein comprising the steps of:
- providing a pair of initially open positioning jaws in a pre-set relation to a path of transport of the toe end of a hose blank past the seamer;
- locating said toe end of said hose blank between said positioning jaws to locate the bead on one side of said positioning jaws;
- causing movement of at least one of said positioning jaws relative to the other of said positioning jaws to close said jaws about said toe end of said hose blank;
- moving said hose blank with respect to said closed jaws until said bead abuts at least one of said jaws, thereby positioning said toe end of said hose blank with respect to said seamer; and
- transporting said toe end of said hose blank past said seamer and generating a closing seam thereacross while maintaining said position of said toe end.
- 2. A method according to claim 1, wherein said closed jaws define a gap therebetween large enough to allow free movement of said blank therein.
- 3. A method according to claim 1, wherein the blank is held immobile by friction between the blank and the carrier.
- 4. A method according to claim 1, wherein the blank is transported along the path to the seamer by a movable clamping means.
- 5. A method according to claim 1, wherein said blank is transported past said seamer by a transport belt moving over an opposed stationary support surface, such that said blank is nipped therebetween and conveyed in a straight line past the seamer by the belt.
- 6. A method as defined in claim 1 wherein, after closing said jaws are reopened adequately to permit transport of said toe end of said hose blank therealong while precluding passage of said bead therethrough.
- 7. A method as defined in claim 1 wherein said positioning jaws guide the bead to said seamer as the hose blank is transported therealong to said seamer.
- 8. A method as defined in claim 1 comprising further mounting said hose blank on a carrier and moving said carrier along a path that will transport said toe end past said seamer while holding said blank immobile on said carrier.
- 9. A method of closing the toe end of a hose blank which terminates in a bead or barrier on a toe closing machine on which the toe end of the hose blank is transported past a seamer which generates a closing seam therein, comprising the steps of:
- providing a pair of initially open positioning jaws in a pre-set relation to a path of transport of the toe end of a hose blank past the seamer;
- mounting a hose blank on a laterally expandable carrier;
- advancing the toe end of said blank through said open positioning jaws by movement of said carrier to locate the bead on one side of said positioning jaws;
- causing movement of at least one of said positioning jaws relative to the other of said positioning jaws to close said jaws about the toe end of said hose blank;
- retracting said hose blank longitudinally on said carrier until said bead abuts at least one of said jaws, thereby positioning said toe end of said hose blank with respect to said seamer;
- laterally expanding the carrier to stretch the hose blank and thereby to hold the hose blank immobile;
- moving said carrier having said hose blank immobilized thereon along said path past said seamer; and
- generating a closing seam across the toe end of said hose blank with said seamer while maintaining said position of said toe end.
- 10. A method of closing the toe end of a hose blank having an enlarged element at said toe end of said blank comprising the steps of:
- mounting said hose blank on a carrier therefor with said toe end flattened and adjacent an outer end of said carrier;
- disposing said toe end of said blank between a pair of jaws with said enlarged element being located on a side of said jaws opposite to said carrier, said jaws being pre-set relative to a path of transport of said jaws being pre-set relative to a path of transport of said toe end past a seamer for generating a closing seam across said toe end;
- bringing said enlarged element into contact with at least one of said jaws to locate said toe end in a predetermined position relative to said path past said seamer; and
- transporting said hose blank along said path and past said seamer while maintaining said predetermined position of said toe end relative to said path to properly locate the seam across said toe end of said blank.
