Abstract
A method and apparatus are disclosed which provide a plurality of stitching machines which may be synchronized without mechanical coupling of the stitching machines. Each of the plurality of stitching machines are connected to a control, which coordinates operations of the stitching machines, including the download of patterns to be stitched by the stitching machines. A master stitching machine is selected by either the control, or the stitching machines. Each of the stitching machines, during stitching operations transmits a heartbeat signal to the master stitching machine. The heartbeat signal can include information related to stitching operations, which the master can use to determine that each stitching machine is operating properly. Several clusters of stitching machines may also be present, with each cluster having a master stitching machine.
