Abstract: An apparatus for bottom folding and stacking of continuous strip of pre-folded paper is disclosed in which a reciprocating frame having a pair of belts defining a gap therebetween is reciprocated within a stationary frame beneath a pair of spaced-apart edge guides. Each belt is supported on a set of transverse rollers journalled in the inner frame and is preferably affixed at both ends to its respective edge guide.Pre-folded paper strip continuously fed from a printer is drawn upwardly through the gap as the gap is reciprocated between the edge guides and is folded and stacked at the bottom of the stack, thereby allowing paper first printed to be inspected or removed without disturbing the stack.

Abstract: A tape roll hold-down device for retaining a roll of tape upon a mounting post includes a transversely extending support surface for engaging and supporting the underside of a hub of a roll of tape. The support post extends upwardly through the plane of the support surface and carries a pivotable toggle mounted upon a pivot pin extending transversely of the post. The toggle includes a pair of wedge portions whereby the toggle can be first pivoted transversely of the axis of the support post and then thrust in a wedging manner between the pivot pin and the adjacent surface of the tape roll hub. In releasing the toggle in one embodiment, it needs merely to be thrust beyond the edge of the opening in the hub so that lifting the hub will pivot the distal end of the toggle upwardly and the pivoting end downwardly into the opening of the hub as the hub is lifted.
