Abstract: An improved prefeeder assembly for shingling planar sheets in which a sheet stack is positioned on a prefeeder lift conveyor which lowers the sheet stack into a floor pit to incrementally elevate the sheet stack. A block pusher assembly sequentially pushes bock segments to a conveyor assembly where a shingling assembly shingles the sheets. A bottom sheet removal assembly having an in-path diverter plate contacts and diverts only the bottom sheet of the bottommost block segment as this block segment is being shingled. As shingled sheets are discharged to other process equipment, a tamping assembly tamps the sheet edges for uniform restacking.

Abstract: An apparatus for forming a rolled tab on a roll of plastic film including a trunion roller-type conveyor apparatus and a traction device having a tractional surface wherein a roll of plastic film contacts the traction device such that the leading edge of the roll of plastic film is grabbed and rolled back to form a rolled tab for the roll of film when a roll of plastic film comes in rotational contact with the traction device.

Abstract: An apparatus and process for forming a rolled tab on a roll of plastic film comprising a traction member or device such as an elongated support member adapted to be inserted in a parallel position between roller members of a trunion-type conveyor apparatus, said support member having a tractional surface for grabbing and rolling the leading edge of a roll of plastic film such that a rolled tab for the roll of film is formed when a roll of plastic film comes in rotational contact with the traction member.

Abstract: A combination bow hoist and arrowhead wrench comprising a flexible cord securely attached to a substantially rigid body having means to compactly and securely store the flexible cord, means for securely holding a bow for raising the bow to an elevated position and wrench means for attaching arrowheads to arrow shafts.

A bottom sheet removal assembly having an in-path diverter plate contacts and diverts only the bottom sheet of the bottom most block segment as this block segment is being shingled. As shingled sheets are discharged to other process equipment, a tamping assembly actuated by balloon cylinders serve to tamp the sheet edges for uniform restacking.

Abstract: A tree stand comprising a stand portion adapted for releasable attachment to a loop formed from an elongated flexible member that is placed in circumferential relationship with a tree or post.

Abstract: Method and apparatus adapted for use on a conveyor line to form a rolled tab in the tail end portion of a roll of plastic film wound on a core. The tail end portion is untreated and initially extends around the surface of the roll to which the tail end portion adheres and terminates at a tail edge. The apparatus comprises a bucket which is connected to the conveyor line for movement thereon and has a floor and wall extending therefrom. The floor of the bucket has a tractional surface supporting the roll and the wall has a substantially frictionless surface pushing the roll in the direction of the conveyor line. The apparatus further comprises drive means, extending in stationary position substantially parallel to the conveyor line and having a resilient tractional surface being compressed into rotational contact with the roll, for rotating the roll.

Abstract: A downstacker assembly in which paperboard blanks, received from a die cutter station, are passed sequentially through a trim removal station, a feed station, a stacker assembly partially disposed in a pit, and a stack retrieval assembly. The stacker assembly is disposed in a drop chute beneath a vacuum conveyor assembly which drops the blanks from the feed station into the drop chute, assisted by a pair of twin blank striker assemblies which selectively separate the blank therefrom. The stacking blanks are tamped using a semiflexible tamper plate assembly against flexible curtains on a descending elevator assembly. A stack staging assembly serves as a temporary cradle to catch the falling blanks once a predetermined stack height is achieved until the stacks can be removed via the stack retrieval assembly. A dunnage holding assembly provides multiple-tier load forming as the stacks are discharged from the downstacker assembly.

Abstract: A slip sheet removal apparatus for removing a dunnage sheet disposed beneath a paperboard blank stack conveyed by a conveyor assembly, the slip sheet removal apparatus comprising a dunnage sheet removal assembly having a stationary subassembly with roller driven drive belts and a retractable subassembly with guide belts thereon. Fluid actuators selectively raise and lower the retractable subassembly to engage a leading edge of the dunnage sheet as it advances on the conveyor assembly to pull the dunnage sheet underneath the conveyor assembly for storage and later removal. Also, a pivot conveyor assembly receives the paperboard stack from the conveyor assembly to alter the direction of travel thereof if required.

The stacker assembly is disposed in a drop chute beneath a vacuum conveyor assembly which drops the blanks from the feed station into the drop chute, assisted by an impacting assembly which selectively separates the blanks therefrom.

A stack staging assembly serves as a temporary cradle to catch the falling blanks once a predetermined stack height is achieved until the stacks can be removed via a stack retrieval assembly.

Abstract: A method and apparatus for cutting predetermined lengths of panels from a continuous strip of flexible material and for forming the lengths of panel members to have a preselected panel profile. The strip is reel fed to a first strip driving station which drives the strip through a shearing station, over a hump table, to a second strip driving station and through a strip forming station. In sequence, the second strip driving station brakes the leading portion of the strip to effect a strip hump over the hump table, which is detected by a protoelectric sensor for hump height and signals the first strip driving station to vary its feed rate to maintain the hump; the second driving station is then signaled to commence driving the lead portion of the strip to the strip forming station.
