ABSTRACT:
A machine for sewing a binding tape to a cut edge of carpeting comprises a wheel-mounted sewing machine having an opposed pair of pinch rollers engaging opposed sides of the carpeting, the pinch rollers being inset from the cut edge and one of the rollers being intermittently motor driven in synchronism with the reciprocating movement of the sewing machine's needle assembly. As the one pinch roller is driven, the sewing machine moves along the floor as the binding tape is played from a reel, folded longitudinally and stitched to the carpet edge. The machine incorporates a spring-biased needle guide which effectively surrounds the needle shank as it moves reciprocally up and down to create the stitches. This guide prevents deflection of the needle and possible breakage thereof should it encounter a hard object, such as a glue bead or the like in the carpet backing. The wheels on which the sewing machine rides are mounted on the bottom on a pan-shaped base which supports the sewing machine and prevents soiling of the carpet by lubricating grease. The pan-shaped base also shields certain of the mechanical linkages of the sewing machine from damage incident to rough handling.
