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 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.

Abstract: A collapsible bag is disclosed which when expanded is capable of sustaining and absorbing impact and which is suitable for use in physical conditioning activities such as karate punching and kicking techniques. An elongate flexible casing is provided which is supportable at one end. A collapsible envelope, which may be an inflatable air bladder, is disposed within the casing. A portion of the exterior surface of the bladder defines a cavity or recess for receiving a weighting material. Sufficient weighting material is disposed in the cavity to impart to the bag a desired impact absorption characteristic. The bladder is inflated by the user of the bag to cause the bag to be hardened to a desired level.
