Abstract: Photographic processing of a plurality of film discs is accomplished by rotating the discs partially immersed in chemical solutions. Processing trays, which contain the solutions, conform to the peripheries of the discs, reducing the volumes of the solutions and making single use batches of the solutions attractive. Single and multiple-tray approaches are included and, at least in the latter case, a transport mechanism is provided for transferring the discs from tray-to-tray while rotating the discs between the trays.

Abstract: Apparatus for and method of attaching a strip of a first material having a hot melt adhesive on both sides thereof to a second web of material. A web of first material is advanced toward and through a cutting station a distance substantially equal to the width of the strip to be formed therefrom and a strip is cut from the end of the web. The cut strip is held on the moving cutting member and is transferred to an anvil on a rotary transfer drum while the drum is stationary. The transfer drum is then rotated, with the strip on an anvil thereof, to a tacking station where a second web of material is supplied at a substantially constant velocity. The strip on the anvil is moved through the tacking station at a velocity substantially equal to the velocity of the second web and is brought into contact with a first surface of the second web.
