摘要： A bundle breaker includes upstream and downstream breaking supports, platens over the breaking supports and actuators for moving the platens toward and away from the breaking supports. Each of the platens includes a plurality of air bladders each having a bottom contact surface facing one of the breaking supports. The actuators move the platens to selectively clamp a log between the bottom contact surfaces of the air bladders and the breaking supports. A third actuator shifts an input end of the downstream breaking support relative to an output end of the upstream breaking support from a first position to a second position to break a first portion of the log from a second portion of the log.

摘要： A conveyor configured to transport sheets along a transport 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. 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 wheels are shiftable in the third direction relative to the belts and relative to the main frame.

摘要： An agitator for agitating sheets of material passing through a sheet transport device that has upper and lower guide sections defining a sheet transport path therebetween. The agitator includes first and second sets of rollers each having a roller axis of rotation and a width, and the rollers are mounted to at least one holder such that the axes of rotation of the rollers are radially spaced from a line and such that rotating the at least one holder around the line causes the rollers to orbit around the line. At least one support supports the holder for rotation around the line, and the set of first rollers is spaced from the set of second rollers in the direction of the line by a distance greater than the width of the rollers. Also a sheet transport device including the agitator.

摘要： A load former includes a frame including a stop wall, a cookie sheet having a top surface parallel to a plane and being movable between an extended position a retracted position relative to the stop wall, and a first platform shiftable between raised and lowered positions relative to the plane. The first platform is positioned relative to the frame such that when the cookie sheet is in the extended position a first portion of the cookie sheet directly overlies the upper surface of the platform and when the cookie sheet in the retracted position no portion of the cookie sheet directly overlies the platform. Also a lift having a lift support and a second platform, the lift being movable relative to the plane and the lift platform begin extendable and retractable relative to the first platform.

摘要： A bundle breaker includes first and second platens located above upstream and downstream breaking supports and first and second actuators configured to move the platens to selectively clamp logs between the platens and the breaking supports. A third actuator moves the second breaking support relative to the first breaking support to break bundles off the log. A foam sheet is attached to the bottom of each of the first and second platens and is configured to be compressed when the logs are clamped. The bottom surfaces of the foam sheets are preferably at least partially coated with an elastomeric coating or at least partially covered by an elastomeric sheet.

摘要： A front end conveyor includes a frame having a first side and a second side, a lower deck and an upper deck. The lower deck includes a plurality of sheet supports, and upper portions of the sheet supports lie in a first plane. The upper deck includes a plurality of sheet guides that define with the sheet supports a sheet transport path through the front end conveyor. A chad wall extends transversely to the sheet transport direction and has a top edge located below the sheet transport path and a front surface facing in the upstream direction and a plurality of fingers projecting from the front surface in the upstream direction. The top edge of the chad wall is positioned relative to the sheet transport path such that hanging chads depending from the sheets will impact the chad wall.

摘要： A conveyor includes first and second support shafts and at least one belt supported between the first and second support shafts that has an upper load-carrying portion and a lower return portion. A first gear is connected to the first support shaft, a second gear is connected to the second support shaft and a drive chain or belt is supported by the first and second gears and has an upper run and a lower run. The upper run includes a tension control device for maintaining a tension on the upper run and the lower run includes an arrangement for displacing a portion of the lower run in order to rotate the first gear in a first direction and the second gear in a second direction opposite the first direction to increase a tension of the upper load carrying portion of the at least one belt. Also an associated method.

摘要： A sheet stacking system includes a conveyor having a discharge end, a hopper at the discharge end configured to receive the sheets ejected from the discharge end and guide the sheets as they fall in a cascade path onto a platform associated with the hopper, the falling sheets forming a main stack on the platform, the hopper including a backstop facing the discharge end of the conveyor such that the sheets ejected from the discharge end impact against the backstop before forming the main stack, and a first accumulator having at least one first support extending through the backstop and shiftable from a retracted position to an extended position, the at least one first support being movable vertically relative to the backstop in the extended position from a raised location outside the cascade path to a lowered location in the cascade path.
