Abstract
A sheet material butt-joining apparatus provides improved joining strength and accuracy between starting and finishing ends (S1, S2) of a sheet material S, by keeping the distance between these ends (S1, S2) of the sheet material (S) at a predetermined value by means of a control pin (63). A motor is continuously operated even after the starting and finishing ends (S3, S4) of the sheet material (S) are held by top and bottom joining pawls (48, 49, 36, 37). In this instance, a cam follower (95) moves in a slot (94) to temporarily stop transfer of a vertically moving force to a vertically movable base (26). On such occasion, the control pin (63) is lowered and retracted from an intermediate position between the starting and finishing ends (S1, S2) of the sheet material (S) to form a gap between these ends (S1, S2). The starting and finishing ends (S3, S4) held by the joining pawls are prevented from deformation or the like.
