Abstract
A thin-web frame feeding device for intermittently feeding a thin-web frame at a predetermined pitch along a guide rail has first and second shafts supported by bearing stands for synchronized axial sliding motion in the same direction and for rotation in opposite directions. The first and second shafts are provided with feeding claws rotatable in accordance with the rotation of the shafts into and out of positions where spontaneous portions of the thin-web frame are clamped. The feeding claws are axially moved in accordance with the axial sliding movement of the shafts to feed the thin-web frame.
