2065020 9103120 PCTABS00003 The invention relates to a device for the automatic clamping and releasing of film material (25, 25') on and off the recording head (9) of a reproduction device using a vacuum arrangement. The device consists of a roll-film cassette (3), a transport and guide surface (20, 21), a film cutter (26), a film length measuring device (32), a pressure device (61) with a pressure roller (61'), a release device (66) with a release finger (68) and drives (22, 23, 54) to rotate the recording head (9) and transport the film material (25, 25'). The recording head (9) has axial rows of suction apertures (38') to clamp the film material (25, 25') by means of a vacuum. A vacuum distributor (95, 96, 97, 98) controllable by the rotary movement is fitted in the recording head (9) and, during clamping, successively connects the individual rows of suction apertures (38') with the fixed vacuum pump (44) so that, as the recording head (9) rotates, the film material (25, 25') is pressed against said rows (38') in stages. The device makes it possible for film material of various sizes, especially large formats, to be automatically conveyed without creasing and delays and to be securely held on the recording head (9) during exposure.
