Abstract
A workpiece holder which is attachable to the positioning apparatus of an automatic sewing machine includes a plurality of sharp pointed pins extending upwardly from a base plate. The workpiece which may comprise one or more individual elastic pieces is mounted on the sharp pointed pins. A cover plate, pivotally attached to the base plate, covers the thus mounted workpiece in such a manner that the sharp pointed pins are shielded from contact with the operator of the sewing machine.
Claims13
A workpiece holder which is attachable to positioning apparatus associated with the sewing head of an automatic sewing machine whereby the workpiece holder can be automatically positioned with respect to a reciprocating needle in the sewing head so as to allow a workpiece held within the workpiece holder to be sewn said workpiece holder comprising:
- a base plate having a plurality of spaced, sharp pointed pins which extend upwardly therefrom so as to define a pattern of spaced, sharp pointed pins that receive an elastic workpiece that is smoothly mounted thereover;
- a cover plate, pivotally attached to the base plate, and having a pattern of spaced holes therein which acommodate the spaced, sharp pointed pins when said cover plate is latched with respect to said base plate;
- means, on the cover plate, for shielding the sharp points of said sharp pointed pins from inadvertent contact with the operator of the sewing machine who handles the workpiece holder during the normal processing of the workpiece holder;
- and
- means on the base plate for attaching said base plate to the positioning apparatus of the automatic sewing machine whereby the workpiece holder can be automatically positioned with respect to the sewing needle of the automatic sewing machine without said shielding means interfering with the sewing needle.
A device for holding a plurality of pieces of work that are to be joined and sewn together, said device comprising:
- a base plate having a first plurality of sharp pins located around the periphery of an opening which allows a reciprocating sewing needle to pass therethrough so as to sew the pieces together;
- and
- a hinged cover plate having a plurality of holes therein which accommodate the sharp pins that extend therethrough when said cover plate is pivoted downwardly over the base plate said cover plate furthermore having individual means for shielding each sharp pin extending through a respective hole.
