Eine verbesserte Transportvorrichtung zum Transportieren von Signaturen von einer sich kontinuierlich bewegenden Sattelkette (1) umfaßt ein erstes Band (7) und ein zweites Band (8), die einander gegenüber angeordnet sind. Eine Signatur, die sich mit konstanter Geschwindigkeit auf einer Sattelkette (1) bewegt, wird zwischen dem Bandpaar (8, 7) gegriffen und von der Sattelkette (1) weg zu einer Bearbeitungsstation (30) beschleunigt.
摘要:
A photosensitive material discharging apparatus includes a discharge roller pair 41, 43 disposed in an outlet for discharging for a photosensitive material, and a plurality of transport roller pairs 70a, 70b arranged on a transport path upstream of the discharge roller pair. The discharge roller pair has a first roller 41 rotatable at a higher peripheral speed than the transport roller pairs, and a second roller 43 disposed to pinch the photosensitive material with the first roller. The second roller is freely rotatable to cause slippage between the first roller and the photosensitive material when the photosensitive material is pinched by both transport roller pairs and discharge roller pair, and to allow the photosensitive material to be transported reliably by drive of the first roller when the photosensitive material is pinched only by the discharge roller pair.

Ein Falzapparat umfaßt eine Transportband-/Niederhalteradkombination, um Signaturen beispielsweise von einem Bandsystemausgang aufzunehmen. Die Transportband-/Niederhalteradkombinationen bremst die von dem Bandsystem (20) kommenden Signaturen (10) ab und kreiert einen geschuppten Ausgabestrom von Signaturen (10). Eine Anzahl von Transportsystemen-/Niederhalteradkombinationen kann zum Erlangen einer gewünschten Geschwindigkeit und der Einstellung eines bestimmten Signaturenabstandes eingesetzt werden.
摘要:
A sheet feed/discharge roller mechanism (15) that includes a plurality of driving rollers (1) and a driven roller shaft (4) disposed in the roller mechanism (15) that is freely displaceable to the driving rollers (1). A plurality of driven rollers (5) are mounted on the driven roller shaft (4) in facing relationship with the driving rollers (1). A plurality of roller supporting members (7) apply forces to the driven roller shaft (4) for biasing the driven rollers (5) towards the driving rollers (1). The forces applied to at least one of the driven rollers (5) is greater than the forces applied to at least a second driven roller (5).

A printer (1) and portable stations (2,3) wherein paper is moved upward from the printer into a U-shaped guide (1a) by pinch rollers (6,7) and then moved laterally by pinch rollers (8,9) in the guide. Similar rollers are in further guides (1b,1c) to direct the paper to the selected station and then downward.
摘要:
Pour éliminer la tendance de livrets composés de feuilles empilées et pliées suivant une ligne centrale de se rouvrir après pliage, on propose un dispositif de finition du pli comportant deux paires de rouleaux 10, 12 parallèlles et opposés sur le trajet des livrets. La normale sur le plan défini par les axes de la deuxième paire de rouleaux est inclinée par rapport à la direction d'avancement des livrets. Par une courroie 20 traînée autour des rouleaux inférieurs 10b, 12b, ou par une tôle de guidage appropriée, les livrets sont forcés sur un chemin courbe en direction de la fente de passage formée par la deuxième paire de rouleaux 12, pour provoquer une force de traction par laquelle les fibres du papier sont brisées à l'endroit du pli.
摘要:
The invention relates to over and under delivery sheet accumulators. Prior sheet accumulators required considerable time to adjust the accumulator for pass-through, under or over sheet delivery. The present invention solves this problem by providing a retractable ramp mechanism which allows for quick and easy adaptability to optionally over or under accumulate and to optionally pass-through sheets without accumulation into stacks. The retractable-ramp accumulator includes driven endless elastic belts (10, 12) to feed sheets therebetween along a sheet-feeding path (24), a sheet stacker (26) having a stacking location and including a selectively releasable stop gate (16), and at least one selectively retractable ramp (14) for selectively deflecting sheets out of the sheet feeding path (24) for selectively feeding under or over previous sheets that are stopped in the stacking location by the stop gate (16). In one embodiment, an upper and lower set of ramps (37, 76) are arranged such that while one set of ramps is retracted, the other set of ramps is interposed in the sheet feeding path (24), so that sheets can selectively be "over" or "under" accumulated.
摘要:
A system for changing the speed of conveyed sheets (10) while maintaining the sheets in register including a speed changing belt (18) operating at a constant speed (V1) to present a radial outer surface portion which travels over a cylindrical guide (23) and into tangent contact with the surface of the sheet travelling at a speed equal to the velocity of the incoming sheets. A portion of the speed changing belt includes an acceleration lobe (30) positioned to engage the trailing portion of the sheet and to provide a continuously increasing radius at the tangent contract portion as the belt (18) travels around the pulley (23) whereby the outer surface velocity of the lobe and the sheet in contact therewith continuously increase from the incoming speed to a desired second speed (V2). The constant velocity speed changing belt (18) requires only a simple constant speed drive and the speed change lobe (30) attached to the belt requires only a relatively small increase in the effective radius of the belt around the cylindrical guide such that unacceptable vertical displacements of the sheet from the plane of travel are obviated. Only the mass of the sheet or other product being conveyed (and an upper holddown idler roll if used) is subject to acceleration (or deceleration) forces as all the machine drive components run at constant velocity during the speed change, thereby minimizing the overall inertial effects.
摘要:
A cash dispensing unit includes first and second cooperating endless belt means (72,74) for feeding a stack (76) of currency notes to an exit port (54). End portions of the first and second belt means (72,74) respectively pass around first and second pulley means (52,66), the first pulley means (52) having a fixed axis of rotation. The second pulley means (66) are rotatably mounted on one end of rockably mounted arm means (56), and third pulley means (64) are rotatably mounted on the opposite end of the arm means (56), the third pulley means (64) being in engagement with part of the second endless belt means (74) which is in cooperative engagement with the first belt means (72). The first and second belt means (72,74) are resiliently stretchable and tensioned whereby the first and second pulley means (52,66) are urged together so that when the stack (76) is positioned at the exit port (54) it is resiliently gripped between the first and second belt means (72,74).
