Abstract: A device for applying spaced layers generally transversely across an elongate web which defines a through path for the web including parallel inlet and outlet path portions spaced sideways from each other and a transverse path portion between adjacent terminal and beginning ends of the inlet and outlet path portions. The web is moved lengthwise at a predetermined speed in a first direction along the inlet and outlet path portions, the device periodically moves the portion of the web along the transverse path portion generally edgewise in a direction parallel to the first direction and at about the predetermined speed to essentially stop longitudinal movement of the portion of the web along the transverse path portion; and the device applies a layer of material such as tape generally transversely across the portion of the web along the transverse path portion as it moves tangentially by the periphery of a rotating applicator drum.

Abstract: An automatic film threading device adapted for use with cameras or projection devices will drive the free end of the roll of film from a magazine along a film path and into the equipment. The threading mechanism comprises a drive for the reel and means for spreading the mouth of the magazine to free the film from the magazine. A second member moves into contact with the outer surface of the wound film to strip the free end from the roll of film and thread the same into a nip area between two drive rollers. The stripping member is biased toward the wound roll of film and a roller near the stripping finger engages the outer convolution of the wound film to hold the roll as the stripping finger contacts the film to direct the free end of the film off the reel.
