Abstract: A film-mount structure comprises a relatively stiff face sheet and a backing sheet which can be peeled off to expose an adhesive for receiving, in a removable and replaceable manner, a film strip for retention and viewing. In order to protect the cellulose-based face sheet from partial separation when the radiographic film is peeled from the adhesive surface, a thin mylar sheet is adhesively attached in a substantially permanent manner to the face sheet, and the releasable adhesive is applied directly to the other side of the mylar sheet. In this way, the film mounts' reusable feature is retained while maintaining the integrity of the face sheet.

Abstract: A wrapping machine for U-folding a sheet of wrapping film or material around a group of cigarettes which are being conveyed along a longitudinal path to a wrapping station. The sheet of wrapping material is fed transversely into the path at the wrapping station and held there by a pair of suction rollers. Reciprocating longitudinally along the path is a receiver into which the group of cigarettes is conveyed. Before the group of cigarettes reaches the wrapping station, the forward end of the receiver engages the sheet of wrapping material and strips it from the suction rollers to form a U-shaped fold about the group of cigarettes as the group moves forwardly out of the receiver into the wrapping station. Thus, the group of cigarettes itself is not subjected to the stress required in removing the wrapping material from the suction rollers.
