A belt-like material stably transferring apparatus an absorbing and feeding apparatus for continuously absorbing and feeding the belt-like material by use of a difference in air pressure. The absorbing and feeding apparatus comprises a reserving chamber for absorbing and feeding the belt-like material to be reserved therein, and a pressure detecting chamber connected to the reserving chamber through a slit. The reserving chamber has an opening portion for feeding the belt-like material, and blowers and are connected at a position, which is opposite to the opening portion. The pressure of the pressure detecting chamber is changed in accordance with the change of the pressure in the reserving chamber connected to the pressure detecting chamber through the slit. The pressure of the reserving chamber is changed in accordance with the amount of absorbing and feeding the belt-like material absorbed and fed to the reserving chamber. Due to this, the pressure of the pressure detecting chamber is detected by pressure detectors, thereby the amount of absorbing and feeding the belt-like material absorbed and fed to the reserving chamber is detected. The belt-like material stably transferring apparatus comprise analog cards for controlling the amount of supplying the belt-like material based on the amount of absorbed and fed belt-like material.

The device (100) is destined to receive flanked continuous strips (1, 2) from an arrival line (L), and feed them towards a transversal cutting station (SR). The device (100) comprises: a basin (3), associated to a terminal part of the arrival line (L), destined to enable formation, in each of the strips (1, 2) of a free loop (A1, A2) in a downwards direction; deviator organs (4), at a 45° angle, provided downstream of the basin (3), destined to guide the strips (1, 2) such as to orientate them perpendicularly to the arrival direction, horizontally centred and correctly staggered in height such as to enter the transversal cutting station (SR).

A perforator apparatus for continuous photo film includes a perforator unit having a punch and a die. The perforator unit is disposed between first and second suction chambers. The photo film is extended past each of the suction chambers. A blower applies suction of air through the suction chambers, to apply tension to the photo film through the perforator unit. The perforator unit is disposed between a feed roller and a sprocket roller, which convey intermittently the photo film by a punching length. A first pass roller continuously conveys the photo film into the first suction chamber. A first loop of the photo film in the first suction chamber is maintained with a length substantially of an arc of a semi-circle defined between the first pass roller and the feed roller. A second pass roller continuously conveys the photo film from the second suction chamber. A second loop of the photo film in the second suction chamber is maintained with a length substantially of an arc of a semi-circle defined between the second pass roller and the sprocket roller. The perforator unit forms a train of perforations in the photo film along each of its two edges when the photo film is stopped.

A vacuum box (38) is provided with recesses (86, 88, 90, 92) on the inner surfaces (74, 76) of its front and/or back walls (40, 42) along at least two of its interior corners (78, 80, 82, 84); so that, the pressures on opposite sides of the incoming and outgoing spans (64.sub.i, 64.sub.o) of the web (50) are substantially equalized at discrete locations along the lengths of the spans, whereby differential pressure applied to the central curved loop (64) between the spans causes the incoming and outgoing spans to remain substantially out of contact with the side walls (40, 42). The side walls (44, 46) may be provided with chamfers (154, 156) at the interior corners or bores (158; 166-172) and ports (160-164; 174-180) to facilitate equalization of the pressure to facilitate equalizing the pressure on opposite sides of webs having a transverse curl toward a centerline of the box. The box may include web keepers (102) to retain the web during thread-up and a removable, sound insulated closure (130). A method of operating such a vacuum box is taught.
