Abstract: A crab trap is described that is movable between an erect condition and a collapsed condition. The crab trap includes top and bottom panels each with a plurality of edges. A pair of opposing side panels are pivotally and hingedly connected to a corresponding one of the edges of the bottom panel. A pair of opposing end panels are also pivotally and hingedly connected to a corresponding one of the edges of the bottom panel. Each of the panels is comprised of a mesh material. Each of the upper edges of the end panels is releasably secured against a corresponding one of the edges of the top panel. The side panels are pivotally movable between a closed position wherein the side panels extend substantially perpendicular to the top and bottom panels and an open position wherein the side panels extend substantially parallel to the top and bottom panels when the crab trap is in the erect condition.

Abstract: A web spreading apparatus that includes a set of spreader rolls spaced from each other in the machine direction of web formation with the axles of the rolls extending generally in the cross-machine direction of web formation. The set of spreader rolls includes a first upstream group of curved rolls and a second downstream group of rolls. Each roll in the downstream group has a central region having less curvature than the end regions joining the central region.
