A front end conveyor includes a frame having a first side and a second side, a lower deck including a plurality of sheet supports and an upper deck including a plurality of sheet guides. Upper portions of the sheet supports lie in a first plane, and the plurality of sheet supports and the plurality of sheet guides define therebetween a sheet transport path for moving sheets in a sheet transport direction toward the downstream end of the front end conveyor. At least one helical brush is positioned at the sheet transport path and is configured to engage scrap material on the plurality of sheets. The conveyor also includes a drive configured to rotate the helical brush.

A front end conveyor has an upstream end and a downstream end, a lower deck including a plurality of primary sheet supports and an upper deck including a plurality of sheet guides. Upper portions of the primary sheet supports lie in a first plane and the sheet supports and sheet guides define a sheet transport path for moving sheets in a sheet transport direction. A pivotable sheet support extends from an upstream end of the lower deck and has at least one surface lying in a second plane. The pivotable sheet support is pivotable from a first position in which the second plane forms a first angle with the first plane and a second position in which the second plane forms a second angle with the first plane, the second angle being different than the first angle.

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.

A conveyor includes a first conveyor deck having a first plurality of contact elements, each having a contact surface movable around a closed path from a contact region to a non-contact region, the first contact regions lying in a plane or being bounded by the plane and a second conveyor deck having a second plurality of contact elements, each having a contact surface movable around a closed path from a contact region to a non-contact region, these contact regions lying in a second plane or being bounded by the second plane. The transport path of the conveyor is defined by the contact surfaces of the first and second contact elements in the contact regions, and the first plurality of contact elements are belts and the second plurality of contact elements are wheels.

A conveying apparatus includes an upper conveyor and a lower conveyor, the top of the lower conveyor facing the bottom of the upper conveyor and defining with the bottom of the upper conveyor a sheet transport path. An air duct having an opening facing the top of the upper conveyor is mounted over the upper conveyor, and a fan is provided that is in fluid communication with the air duct. The fan draws air through the opening, into the air duct and out an exhaust vent. A housing substantially encloses the upper conveyor and the lower conveyor and is connected to the air duct, and the housing has a bottom opening located below the sheet transport path such that a majority of the air drawn through the opening by the fan passes through the upper conveyor.

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 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 packaging assembly (10) that includes a weighing machine (11) that delivers batches of product to a packaging machine (18). A film drive assembly (17) pulls strip bag material pass a former shoulder (41), to form tubular bag material into which batches of product are to be delivered, with the tubular bag material being longitudinally sealed, transversely sealed and transversely cut by the packaging machine (18).
