Abstract: A method of employment of automatic lengthwise receivers which equip continuously operating corrugators. In accordance with the invention the course of the last panel of a first form and size is followed from its arrival upon the receiver, and a change of stack is triggered when this last panel has left the final conveyor of the receiver. Furthermore any retraction of the telescopic device located downstream from first conveyor of the said receiver is stopped.

Abstract: A garment stacking apparatus having a pair of belts travelling together at the same speed in which one belt provided with polyurethane on its surface feeds and urges a garment section on the second belt provided with a frictionless shutter and open space and, when the first belt is suddenly stopped while the second belt continues its movement, the garment section slides from the frictionless shutter onto the open space and drops into a receptacle.

Abstract: Folded signatures of lightweight stock are fed in a direction parallel to the backbone of the signatures and deposited in sets of predetermined number and in shingled relation onto a main conveyor moving transverse to the direction of feed from the supply stack. The main conveyor deposits the signatures on the top of a stack in the hopper of a gathering machine. The height of the stack in the hopper is sensed, and this is used to control feeding from the supply stack. Preferably, the supply stack is held in a hopper with the signatures resting on a second or supply conveyor which extends upwardly and outwardly from the main conveyor so that adjacent loading machines can be nested to reduce space requirements.

Abstract: A stack of sheets is formed in a paper cutter by feeding spaced sheets from a first conveyor to a second and slower conveyor to overlap the sheets which are then fed onto a pallet, the latter being lowered as more sheets are fed. When a stack is near completion the first and second conveyors are decelerated and some sheets diverted from the first conveyor to form a gap in the flow of sheets, the second conveyor only is then accelerated for a period of time to enlarge the gap and then decelerate, both conveyors then being accelerated to normal speed. An auxiliary support is then moved into the path of the sheets falling on to the pallet in the gap previously created. While the completed stack is being removed a new stack is forming on the auxiliary support. The full pallet is replaced by an empty one and the auxiliary support is withdrawn to permit the new stack to drop onto the pallet.

Abstract: An improved burster for separating continuous business forms stationery assemblies into individual form lengths of the type including an infeed mechanism for driving the continuous assembly into a burster which, in turn, separates the assembly into individual form lengths which are placed on a conveyor to be conveyed to a stacking tray. The burster includes a powered mechanism whereby the burster, the conveyor, and a portion of the stacking mechanism may be simultaneously adjusted for various form lengths. Also incorporated is an automatic electrical system responsive to such adjustment for automatically adjusting the conveying rate of the conveyor to insure proper shingling of the individual form lengths thereon. The burster is in a housing having a movable cover whereby access to the various mechanisms may be obtained. A control system provides for jogging of the mechanisms with the cover open that precludes continuous operation for safety purposes.

Abstract: A hopper loader delivers a shingled stream of signatures to a hopper from which the signatures are fed. The hopper loader apparatus is portable and comprises a generally horizontal first conveyor belt section for receiving an array of side-abutted signatures on edge. The apparatus also includes an inclined second conveyor belt section for engaging the side of the signatures and for feeding the signatures from the array in an overlapped stream toward the hopper. The apparatus includes a means for adjusting the speed of the first belt section relative to the second belt section. Also the apparatus includes a presser belt construction which cooperates with the inclined section for pressing on the signatures to provide a sufficient frictional force between the belts and the signatures so that the signatures will be properly moved up the inclined belt section.
