ABSTRACT:
A portable carpet binding machine comprising a housing defining an interior region, a drive mechanism supported by the housing and at least partially disposed in the interior region, a prime mover operatively coupled to the drive mechanism for providing motive power to the drive mechanism, a sewing assembly driven via the drive mechanism for sewing a strip of material to a piece of carpet, the sewing assembly including a binder guide, a sewing needle and a looper, the binder guide operating to fold the strip of material around an edge portion of the piece of carpet, the sewing assembly, when driven, operating to stitch the strip of material to opposite sides of the edge portion of the piece of carpet using first and second pieces of thread. The portable carpet binding machine includes a carpet feeding assembly including a feed driver mechanism and a coacting puller mechanism operating in substantially synchronous movement to linearly feed the piece of carpet relative to the sewing assembly. The feed driver mechanism includes a feed-dog driven via the drive mechanism that intermittently engages the bottom of the piece of carpet to thereby advance the piece of carpet forward. The coacting puller mechanism includes a feed roller driven via the drive mechanism that intermittently engages the bottom of the piece of carpet which, in turn, pulls the piece of carpet forward substantially simultaneously with respect to the advancement by the feed-dog of the feed driver mechanism.
