Abstract:

A semi-automatic leg binding attachment system includes a pair of infeed guide plates leading towards and terminating in a pair of sew heads. To align the garment as it is fed into the sew heads, a combination of pneumatic garment aligners and active, mechanical garment aligners are provided. The pneumatic garment aligners preferably include fine and coarse pneumatic garment aligners attached to the infeed guide plates. A central material blower blows downwards towards the garment to eliminate folds and maintain garment tension against which the active, mechanical aligners pull. Easy operator access during garment loading is provided by devices which disengage the fine pneumatic aligners and the active, mechanical aligners away from the infeed guide plates. To load the garment, the operator lays the garment onto the infeed guide plates and places a leading edge of the garment below material present/foot drop sensors. During the sew cycle, a controller receives signals from alignment detectors and material edge aberration detectors to control the operation of the active, mechanical garment aligners and maintain correct garment alignment.
