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 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 first and second feed rollers driven via the drive mechanism. The first feed roller engages the top of the piece of carpet and the second feed roller engages the bottom of the piece of carpet. The first and second feed rollers pull the piece of carpet forward substantially simultaneously with respect to the advancement by the feed-dog of the feed driver mechanism.
