Japanese Patent JP2503431
Kind Code:

Abstract:
In order to correct the asynchronous state of a feed pulse motor of a sewing machine used to reciprocate a feed for feeding a fabric to a sewing needle, a feed control apparatus is provided which switches the pulse motor to a predetermined excited state when the feed dog abuts a stopper on the downstream side of feed motion at the start up of sewing operation so as to locate the feed dog at a known reference position. Additionally, the feed control apparatus switches the pulse motor to another predetermined excited state when the feed dog abuts a stopper on the upstream side of the feed motion so as to locate the feed dog at a known position during consecutive sewing operation.
