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.
