The present invention relates to a feeder module for a converting machine, the feeder module comprises an upper feeder assembly, and a lower feeder assembly comprising a loading surface configured to receive a stack of sheets. The upper feeder assembly (20) comprises a gauge (32), wherein a distance (d1) between a vertical distal end of the gauge and the loading surface defines a clearance through which a lowermost positioned sheet in the stack can pass at a time. A feed roll assembly (34) located downstream of the gauge comprises an upper feed roller (35a) and a lower feed roller (35b). The lower feeder assembly (22) and the lower feed roller are displaceable in the vertical direction.

In order to obtain a ribbon feeding shaft capable of accurately adjusting a position of a regulating member and preventing a positional deviation, a long sheet material holding device includes a pair of first locking groove trains (91c and 91d) arranged in parallel with each other along the axial direction of the holding shaft (91), the pair of first locking groove trains (91c and 91d) having a series of grooves (61c and 61d) respectively, the series of grooves (61c and 61d) extending across the axial direction of the holding shaft (91), each of the series of grooves (61c and 61d) being provided with slope surfaces (71c, 71d) sloped along the axial direction of the holding shaft (91) and oppositely to each other and perpendicular surfaces (81c, 81d) perpendicular to the axial direction of the holding shaft (91), and a pair of second locking groove trains (92c, 92d) formed in a pair of locking members (92x, 92y) provided in the regulating member 92 inserted into the holding shaft (91), to match the surfaces of the pair of first locking groove trains (91c and 91d).

The invention discloses a sheet processing machine with an alignment plate at the input. The sheets are piled against the plate, and during each machine cycle, the bottommost sheet is extracted and delivered to a gripper bar of the machine. The alignment plate can move precisely longitudinally and diagonally to adjust the position and the skew of the sheet for correct positioning in the gripper bar. The alignment plate is guaranteed to be kept vertical by using a pair of synchronized linear actuators on each side of the plate. The machine can adapt to varying sheet thickness by adjusting the gap below that plate thanks to a motorized gauge. To even better position the sheets, a set of abutments is provided after the plate, and at a fixed distance to the plate. The abutments are pivoting to get out of the way of the gripper bar when needed.

The present invention relates to a paper feeding apparatus. The paper feeding apparatus includes: a main body configured such that a paper discharge outlet, a space, and a door are formed therein; a plurality of guide rails formed inside the main body in vertical directions; a plurality of guide rods formed inside the main body in vertical directions; a paper support plate formed in a plate shape so that paper is stacked and supported thereon, and configured such that a plurality of bushings, insertion grooves, and a multi-stage screw are formed in connection with the paper support plate; a power unit including a motor provided with a driving pulley, a driven pulley, and a chain configured to connect the driving pulley and the driven pulley; and a sensor configured to measure the weight of paper, and a controller configured to control the driving of the power unit.

A media conveying device includes: a delivery cylinder to rotate on an inner circumferential surface side of a medium conveyed along a curved conveyance path; a first guide disc to rotate integrally with the delivery cylinder on an inner circumferential surface side of the curved conveyance path, the first guide disc having an arc-shaped guide surface to come into contact with a first peripheral area of the medium in a width direction of the medium; a second guide disc to rotate integrally with the delivery cylinder on the inner circumferential surface side of the curved conveyance path, the second guide disc having an arc-shaped guide surface to come into contact with a second peripheral area of the medium in the width direction of the medium; and a slide mechanism to slide the first guide disc and the second guide disc in the width direction of the medium.

The present invention is directed to a paper feed system. The paper feed system includes: a paper feed apparatus configured to accommodate stacked paper and sense a paper shortage state and a paper replenishment completion state; a communication unit provided to be integrated with or correspond to the paper feed apparatus, and configured to transmit a paper replenishment request signal when the paper feed apparatus senses a paper shortage state and transmit a paper replenishment completion signal when the paper feed apparatus senses a paper replenishment completion state; and a first server configured to communicate with the communication unit. When a change in the weight of stacked paper is detected, a paper support plate is elevated by driving a motor. When a situation in which the paper support plate reaches a set remaining amount height, a paper shortage state signal is transmitted to feed paper.

Described herein is a sheet supply apparatus for continuously supplying sheets while splicing the leading edge of the sheet of a standby roll to the trailing end of a sheet being unwound from a working roll by using an auto splicer, the sheet supply apparatus including: a turret unwinder provided with fixation chucks that each fix both ends of a paper tube, and configured to switch the positions of the standby and working rolls; a detector configured to detect the position of one of both axial ends of the standby roll; a corrector configured to be connected to each of the fixation chucks and to correct the position of the standby roll; and a controller configured to align an end of the standby roll so that the end of the standby roll is aligned with the end of the working roll while correcting the position of the standby roll.
