Abstract: A sweepline roller-stopper connects a sweepline to a bottom trawl while stopping lateral movement of rollers along the sweepline. In a preferred embodiment, the roller-stopper includes a tubular body member having a large washer welded to an end and a tang welded to a side. A bolt passing through the body member fixes the position of the roller-stopper on the sweepline chain. The roller (or a spacer) abuts the washer, which resists the lateral forces exerted by the roller. In another embodiment, a ring having a tang freely rotates about the body member, while the body member is fixed to the sweepline chain. The roller-stopper is rugged, resists wear, and prevents the trawl net from becoming tangled with the sweepline.
