Abstract: A carpet edge finishing machine having enhanced power through the use of an elongated feed dog is disclosed. As a result, the machine can be used for the most demanding of carpet edge finishing applications and also has sufficient power to pull itself along the edge of the carpet without assistance from the machine operator. In the disclosed embodiment, a serger includes a frame having a planar table over which the carpet moves. A powered roller is located above the planar table and presses downwardly on the carpet edge to forcefully move the carpet. A presser foot is located above the carpet and presses downwardly on the carpet and is located in close proximity to the powered roller. A movable feed dog engages the lower surface of the carpet edge in a reciprocating motion to assist in pulling the carpet. The feed dog is elongated and underlies both the powered roller and the presser foot to sandwich the carpet there between.

Abstract: A portable carpet binder applies and sews a binding tape to a carpet edge. The binder includes a sewing head having a carpet support table, a sewing mechanism, a motor, means for folding the binding tape over the carpet edge, and wheels to move the carpet binder on a floor. The binder operates using a puller having a U-shaped puller bracket, means for mounting the puller bracket on the sewing head above the table, a first longitudinally serrated roller rotatably mounted on the puller bracket, a second longitudinally serrated roller rotatably mounted on the puller bracket parallel to the first roller, and coupling means for rotatably and synchronously coupling the first roller to the second roller so as to transfer rotary motion from the first roller to the second roller. Also provided are driving means for intermittently driving the puller in unidirectional rotation, and timing means for adjusting a timing relation between the driving means and the sewing mechanism.
