Abstract
A cloth feeding apparatus having two feeding devices with respect to the feeding direction and adapted to feed a cloth under a tension by setting the feeding amount on the downstream greater than the feeding amount on the upstream.
Claims11
A cloth feeding apparatus, comprising first and second feeding devices capable of forward and backward feeding, wherein said first feeding device comprises a rotator provided on the downstream to the second feeding device with respect to the forward feeding direction for feeding the cloth in contact therewith, a pulse generator for generating a series of pulses corresponding to the cloth feeding amount in response to the withdrawal, from the cloth, of a needle provided reciprocally movably so as to stitch the cloth on a bed, a step motor actuated by the series of pulses from the pulse generator, said step motor causing said rotator to rotate, and a feeding amount setter adapted to determine the number of the pulses in said series issued from the pulse generator, upon the forward feeding operation, in such a manner that the feeding amount of the rotator is greater than the feeding amount of the second feeding device provided on the upstream to the rotator with respect to the forward feeding direction, whereby the cloth is fed under tension during forward cloth feeding.
