Abstract
A machine for manufacturing shoes by stitching along the border of the shoe with a striker situated inside the upper and positioned in the stitching area of the shoe, comprises a freely rotatable striker supported by an oscillating arm and positioned on the inside of the upper in correspondence of a stitching station. The station is defined by a guide fork situated with its prongs in a horizontal position, with which the striker engages when in its operating position.
Claims12
A machine including a main frame, for stitching a sole to an upper/ready made sole assembly at a stitching station, said station comprising:
- a guide fork having an upper prong and a lower prong, said prongs projecting in a first direction toward a position where an operator would be located in using said machine, said prongs being parallel to each other and including a respective slot in each said prong;
- an upper needle and a lower needle, said needles being curved and opposite facing, said needles being mounted at a right angle to said first direction for passage through said slots in respective semi-circular trajectories and with transverse movements in opposite directions to affect stitching;
- a striker for sliding along an inside part of said sole assembly during stitching, said striker having a first axis and holding a peripheral edge of said sole assembly against said guide fork;
- support means for holding said striker in a position opposing said guide fork for stitching said sole assembly with said needles, said support means including:
- (a) pivotable means connected to said striker for adjustably orienting said first axis of said striker relative to said first direction of said prongs,
- (b) translational means connected to said striker for moving said striker toward and away from said guide fork, and
- (c) rotational means connected to said striker for aligning said peripheral edge of said sole assembly during movement of said sole assembly by said operator in continuous motion relative to said guide fork.
