Abstract: The method of transporting an electrostatic strip wherein the strip on a supply roll is pulled from the supply roll which is normally freely rotatable and the strip having been pulled from the supply roll is returnable to the supply roll by driving the supply roll in reverse to rewind the electrostatic strip; the unspooling of the electrostatic strip from the supply roll is performed by a pair of feed rollers; after imaging the electrostatic strip, it is carried between a pair of longitudinally ribbed guides past a magnetic toner to an inspection station at which station it may be viewed and optionally severed from the remainder of the electrostatic strip, which remainder is returned toward the supply roll for neutralization, detoning, reimaging and refeeding to the viewing station, while the portion of the electrostatic strip at the viewing station is carried in a generally horizontal planar course to a fuser for making permanent the toned, unfused electrostatic image.

Abstract: A first work piece for forming a tube body (3) made of a carton blank which is coated with a fuseable plastic material on one side and which is provided with an opening in the center thereof. In this opening, a second work piece is inserted and fused having a socket and a collar for forming a discharge opening (7). Thereafter, the blank is folded in such a manner that two walls (3a) are generated which are connected with a center segment (3d) having a lens shaped contour containing the discharge opening (7). Thereafter, the side edges of the walls (3a) are fused with each other in pairs, but the end of the tube body (3) facing away from the discharge opening (7) remains open. Subsequently, filler material is filled through the opening and thereafter the edges (3c) of the wall facing the discharge opening (7) are also fused. In this manner, tube like containers can be made, which can be also closed at the discharge end by the first work piece which consists of comparable inexpensive material.
