Abstract: A clasp has a prong and a housing with clamping wedges and actuator wedges. The clamping wedges are spaced circumferentially around the prong within the housing and moveable within the housing via the actuator wedges. In a disengaged position, the clamping wedges are spaced radially outwardly from the outer surface of the prong at a distance sufficient such that a tube is insertable between the prong and the clamping wedges. In the engaged position, the clamping wedges are positioned radially inward of the disengaged position so as to press the tube against the prong. Each actuator wedge is slidingly engageable with the corresponding clamping wedge along complementary and cooperating wedge-shaped surfaces of the actuator wedge and the corresponding clamping wedge. The wedge-shaped surfaces include cooperating elongated protrusions and elongated slots.

Abstract: A method is provided for removing mandrels from successive rolls of convolutely wound web material. In one aspect, a roll of web convolutely wound around a mandrel is moved to a position in which the mandrel is aligned with a clasp with the clasp spaced apart from the mandrel. The clasp is then moved along a path toward the roll. Movement of the clasp toward the roll is stopped only when the clasp is in a position to engage the mandrel. The mandrel is engaged with the clasp. The clasp and the mandrel are moved away from the roll to withdraw the mandrel from the roll. The mandrel is released from the clasp when the mandrel is removed from the roll. The mandrel is removed from the path of the clasp. The steps are repeated for a subsequent roll.

Abstract: A control system for a converting line has a sensor configured to sense a distance between the sensor and a surface of a roll of web material as the roll of web material is unwound from an unwinder and directed to the converting line. The controller is configured to: (i) determine a diameter measurement of the roll as the roll rotates based upon the sensor signals; (ii) store a plurality of data structures in a memory of a controller of a control system wherein the data structures comprise a plurality of data items associated together as the diameter measurements of the roll of the web material; (iii) process by a statistical regression analysis the data structures associated with the diameter; and (iv) generate signals for controlling the converting line based upon the processed diameter measurements.

Abstract: An assembly handles a roll used on a machine in a converting line. A storage assembly has a storage structure that extends above the machine that uses the roll. The storage assembly has a rack for supporting the roll in the storage structure. The rack has a roll mover configured to move horizontally between a stored position and an extended position. A transfer assembly has first and second supports on laterally opposite sides of the converting line. The first and second supports are adjacent to and extending above the machine. The transfer assembly has a lifter that is operatively connected to and supported by the first and second supports. The lifter is configured to move vertically relative to the first and second supports between the storage assembly and the machine. The transfer assembly is configured to transfer the roll between the rack in the storage structure and the machine.

Abstract: In a controller for a converting line: (a) mechanical characterization module generates an estimate of an applied web force at a driven roller based upon velocity and torque signals, and mechanical properties associated with an upstream and downstream roller, one or both of which may be the driven roller; (b) a web stiffness estimator module generates a span stiffness estimate, a previous span tension estimate, and a span time constant based upon the span length, the velocity signals from the upstream and downstream roller sensors, a span tension signal from the span tension sensor, and the applied web force estimate from the mechanical characterization module; and (c) a tension control module generates a velocity trim command signal for the driven roller based on the span stiffness estimate, the previous span tension estimate, a web span time constant, a span tension signal, and a span tension setpoint.

Abstract: A converting line for coreless roll products includes a rewinding machine and a controller. A log of convolutely wound web material is wound in the rewinding machine during a wind cycle. A diameter of the log, a caliper of the web material, and an amount of tension of the web is determined at a plurality of time points during a time period of the winding cycle. The controller is enabled to generate a signal to change an operating condition of the converting line based upon at least one of a diameter determination at a time point during the wind cycle, a caliper determination at a time point during the wind cycle, a wound web amount determination at a time point during the wind cycle, and a tension determination at a time point during the wind cycle.

Abstract: Rolls of an embosser laminator unit may be calibrated with an iterative process of moving axial ends of the roll a set incremental distance until contact between the rolls is made and then making a correction to the distance based upon the end of the roll making contact. The rolls may be move an initial position where the faces of the rolls are devoid of contact with each other. One or both of the rolls may be rotated. The distance between the ends of the rolls may be decreased until the faces of the rolls make contact with each other. The distance between the first ends of the rolls may be increased by an incremental amount, and a determination of contact between the faces of the rolls may be made by alternate movement of the rolls by the incremental amount and position prior to contact.

Abstract: A method for unwinding includes loading a first reel of web material into a first unwind position where the web is unwound. A splicing unit is then moved in the machine direction toward the first unwind position until there is sufficient space to allow a further reel to be loaded into a second unwind position where the web from the second reel is unwound once loaded. Then, the web from the first reel is spliced to the second reel, and the web of the first reel is thereafter cut. The process continues in the opposite direction after removing the first reel from the first unwind position. The web of the second reel is unwound in the second position, the splicing unit is moved toward the second unwind position until there is sufficient space to allow a further reel to be loaded into the first unwind position.
