Abstract: Clutch pressure or servo motor torque profiling is applied to the powered capstan roll in a corrugator web splicer to control tension in the paper in the accelerating new paper roll to bring the new roll up to line speed more quickly and without causing web tear out.

Abstract: A compression or fold completion device used to uniformly compress a folded edge of a workpiece, such as a box blank, in order to allow the blank to more easily be utilized in subsequent packaging operations. The device includes a pressure roller mounted to a rotatable adjustment member. The rotational axis of the pressure roller is offset from the rotational axis of the adjustment member. The adjustment member is in turn connected to an actuating assembly, which may include an arm secured at one end to the adjustment member and at the other end to an extendible and retractable actuator, in order to enable the actuator to rotate the adjustment member and selectively position the pressure roller in engagement with a folded edge of a workpiece passing beneath the pressure roller.

Abstract: A score bend testing apparatus consists of a base having an upwardly facing support surface which supports a scored sheet of material. The support defines a forward edge, and the score is positioned forwardly of the forward edge while the rearward portion of the sheet is clamped against the support by a clamping device. A force gauge assembly is moved downwardly to engage the sheet of material forwardly of the score, and downward movement of the force gauge assembly results in the sheet of material being bent at the score. The force gauge assembly determines the amount of force required to bend the sheet of material. The force gauge assembly is mounted to a cross-member which extends between movable output members associated with rodless pneumatic cylinders.
