A diverter conveyor includes a frame supporting an upper conveyor that has an upstream end and a downstream end and that is configured to carry sheets in a first, downstream, direction. A plurality of nip rollers are mounted on the frame upstream of the upstream end of the upper conveyor and are spaced from the upstream end of the upper conveyor by a gap. The nip rollers feed the sheets along a main path to the upstream end of the upper conveyor. A rejection conveyor is supported by the frame and has a portion beneath the gap and extends away from the upper conveyor at an acute angle. A plurality of paddles are mounted at the first gap, and an actuator is operably connected to the paddles and configured to shift the paddles from a first position out of the main path to a second position in the main path.

A device for cardboard storage and removal for a bridge in a corrugated cardboard production line includes a bridge over which a conveyor system for conveying the single-sided laminated corrugated cardboard web is arranged. The exit end of the conveyor system for conveying the single-sided laminated corrugated cardboard web is provided with a clamping and cutting unit and a movable cardboard storage carriage unit is provided under the conveyor system for conveying the single-sided laminated corrugated cardboard web, under which conveyor system a conveyor belt system is provided in the bridge, and in the bridge an opening is provided, under which a waste cardboard collecting carriage is provided. The movable cardboard storage carriage unit stores the cardboard by means of cardboard storage rolls, which retain the single-sided laminated corrugated cardboard web flat on the bridge. In the event that a splicing defect is detected, the defective piece is cut out by the clamping and cutting unit and ejected by the conveyor belt system to the waste cardboard collecting carriage through the opening. Hence, it follows that productivity is improved.

An automated sheets processing system has a vertical stacks accumulating region (SAR) into which sheets are uninterruptedly fed to build vertical stacks for pre-specified loads including completed loads and newly building nascent loads. A tiltable Stacking Deck has a downstream discharge end from which the sheets can be fed at different elevational levels into the stacks accumulating region. A nascent sheets accumulator system has a plurality of support surfaces that are retractably interjectable into the stacks accumulating region for defining a separation gap between the top of a completed load and the bottommost sheet of a nascent new load. At least one of the support surfaces is retractably interjectable in an upstream direction into the stacks accumulating region while at least two others of the support surfaces are retractably interjectable in a downstream direction into the stacks accumulating region. One of the support surfaces has an anti-scuff feature.

A conveyor for transporting sheets along a path from an input end to a discharge end includes a main frame, an upper conveyor deck supported by the main frame and having a plurality of belts and a lower conveyor deck supported by the main frame and having a plurality of wheels supported by a plurality of shafts. The transport path is defined by the contact surfaces of the plurality of belts in the first contact region and the contact surfaces of the plurality of wheels in the second contact region, and the conveyor is configured such that the sheets make direct contact with the contact surfaces of the plurality of belts and make direct contact with the contact surfaces of the plurality of wheels when the sheets move along the transport path. The lower conveyor deck is shiftable laterally relative to the upper conveyor deck.

A device for determining the quality of a moving corrugated board web with at least one cover web and at least one corrugated web. A quality determination sensor arrangement, which includes a first quality determination sensor unit facing the corrugated board web, is provided for determining the quality of the corrugated board web on its first side, and a second quality determination sensor unit, facing a second side of the corrugated board web opposite the first side, for determining the quality of the corrugated board web on its second side. The device includes an evaluation unit that is in signal contact with the quality determination sensor arrangement and evaluates signals from the quality determination sensor arrangement related to the quality of the corrugated board web.

A buffer apparatus configured to hold a stack of sheets includes an input, first and second side guides each having a face facing transverse to the travel direction, and a backstop facing the input and spaced from the input in the travel direction. The first side guide, second side guide and backstop define a hopper for holding a plurality of the sheets. First and second retractable supports are shiftable from first positions in which a first portion of the respective retractable support projects a first distance into the hopper and a second position in which the first portion of the respective retractable support projects a second distance into the hopper or does not project into the hopper, the second distance being less than the first distance. The at least one second retractable support is located between the input and the at least one first retractable support.

A device for ejecting 1 a flat object 101 during the conveyance thereof along a conveying path 102 includes an inlet conveyor 10 and an outlet conveyor 20 which are successively arranged one after the other along the conveying path 102. At least the downstream part 11 of the inlet conveyor 10 is orientably mounted for pivoting between a conveying position and an ejecting position and at least the upstream part 21 of the outlet conveyor 20 is orientably mounted for pivoting between a conveying position and an ejecting position.

A system for forming and fanfolding a sheet material, from a web of indefinite length, having a bottom, top and longitudinal side edges, the system includes a frame, a feeding device, a creasing device downstream of the feeding device to form transverse creases on the web spaced apart at a constant longitudinal pitch and defining adjacent partitions, and a folding device located downstream of the creasing device for folding adjacent partitions along creases into a fanfold arrangement. The folding device includes at least one first group of thrust tools acting on creases formed on the bottom side of the web and at least one second group of thrust tools acting on creases formed on the top side of the web. The thrust tools of each group are mechanically connected to and operatively dependent on each other so that tools of the same group are forced to follow the same trajectory.

A corrugated paperboard sheet feeding apparatus comprises: a plurality of sheet feeding rollers; a grate formed with a plurality of opening portions for receiving the sheet feeding rollers and configured to switch between contact and non-contact states of the corrugated paperboard sheet with respect to the sheet feeding rollers; and a suction box configured to suck the corrugated paperboard sheet downwardly by gaps between the sheet feeding rollers and the opening portions, wherein each of the gaps is formed to be 10 mm or less, and wherein the apparatus further comprises a mat switch for detecting an entry of a person into an area in a sheet feeding section, and a control device for stopping movement of the sheet feeding rollers and/or the grate when the mat switch is turned on.

A system for applying a material to a substrate comprising: a feed section that comprises a feed roll and configured for advancing a material along a predetermined path; a material applicator roll configured to receive the material from the feed roll and apply a cut length of material to a substrate; a knife element located between the feed section and the material applicator roll; and a non-vacuum anvil roll positioned near the knife element, wherein the knife element and the non-vacuum anvil roll are positioned along the path of the material and engage the material to cut the material into the cut length of material for applying to the substrate, and wherein the material contacts the peripheral surface of the non-vacuum anvil roll only at a cut engagement point.
