Abstract
Method and apparatus are disclosed for registering and clamping the vamp portion of a boot relative to a flat boot shaft. Each side of the vamp portion of the boot is substantially folded in order to achieve registration with the previously registered and clamped boot shaft. Clamping of each substantially folded side of the vamp occurs in such a manner as to not distort the fold. The folded vamp is otherwise securely clamped so as to permit an automatic join and sew operation with respect to the registered and clamped flat boot shaft.

Apparatus for registering and clamping large pieces of work within a pallet that is to be attached to the movable carriage of an automatic sewing machine, said apparatus comprising:
- means for registering and clamping a first flat piece of work within the pallet;
- means for registering only the central portion of a second piece of work relative to the first flat piece of work;
- means for registering one side of the second piece of work relative to the first piece of work after folding the one side of the second piece of work;
- means for clamping the one folded side of the second piece of work adjacent to the fold;
- means for registering the other side of the second piece of work relative to the first piece of work by folding the other side of the second piece of work;
- and
- means for clamping the other folded side of the second piece of work adjacent to the fold therein.
A method for registering and clamping large pieces of work within a flat pallet that is to be attached to the movable carriage of an automatic sewing machine, said method comprising the steps of:
- registering and clamping a first flat piece of work within the pallet;
- registering only the central portion of a second piece of work relative to the registered and clamped first flat piece of work;
- folding one side of the second piece of work so as to thereby register the folded side relative to the first piece of work;
- clamping the one folded side of the second piece of work adjacent the fold;
- folding the other side of the second piece of work so as to thereby register the other folded side relative to the first piece of work;
- and
- clamping the other folded side of the second piece of work adjacent the fold therein.
