Abstract: A rotary drive for a belt tensioner comprises a housing having at least two cylindrical recesses with adjacent wall parts of the housing limiting the recesses. The recesses have at least approximately the form of circle sectors. The rotary drive further comprises a pinion mounted rotatably in the housing, and at least two rotary pistons arranged opposite one another in a respective one of the recesses. The pistons are designed as cylindrical bodies having the form of circle sectors. Each piston extends over a circle arc which is significantly less than the circle arc over which each of the recesses extends, each of the pistons having side faces limiting the circle arc. Each piston is provided with external teeth adapted to engage the pinion. A pressure space is formed between one of the side faces of each of the pistons and the wall parts delimiting the corresponding one of the recesses. The pressure space is adapted to be supplied with a pressurized gas for driving the pistons.

Abstract: A winding machine for winding up webs, possibly longitudinally divided webs, and preferably paper webs. The winding machine comprises two support rollers which support, in a winding bed, the roll to be produced and of which possibly one or both comprise casings which can be deformed, preferably to different degrees. During the winding process, the web running through the spacer gap between the two support rollers partially wraps around one of the two support rollers. The winding machine further comprises a space delimited by the two support rollers, the partly formed roll, and this space has sealed closures on its ends and a sealed closure below the spacer gap between the two support rollers. Finally, the winding machine generates excess pressure in this space in order to balance the inherent weight of the roll.

Abstract: An apparatus and method for rewinding large rolls of paper into smaller rolls, such as bathroom tissue rolls. The rewinder includes three rolls forming a winding cradle and winding control fingers operating adjacent to and in the winding cradle. Upper and lower winding rolls are spaced apart far enough to allow a core to be introduced between them by the winding control fingers. A rider roll moves relative to the winding rolls to control the diameter of the paper roll being wound. The lower winding roll is preferably equipped with two sets of winding control fingers which can orbit around the roll and introduce the core between the winding rolls, separate the web, guide the web around the core and remove the completed log from the winding cradle. Each of a plurality of winding control fingers is equipped with a core insert finger and a web separation finger so that each winding control finger can independently receive, transport and deposit a core in preparation for the winding process.

Abstract: The turn-up of a continuous web from a parent reel to a new spool is made using an apparatus for sensing the presence of the newly cut web about the new spool and moving the new spool about a pope reel drum once the web has begun to wind on the new spool. A signal processing system is provided to monitor the speed of the web, defects in the web, the position of primary and secondary arms, and whether a turn-up has failed. The system provides output signals to control the timing of the turn-up and the motion of the primary and secondary arms. The apparatus may have several sensors for measuring the presence of the web, the speed and elapsed number of turns of the spool, and may have different types of sensors for use with different types of spool materials.

Each secondary unit, includes an outer first secondary member and an inner second secondary member, each of the secondary members having a linearly movable secondary body, an actuator for moving the secondary body, and a press device to maintain a predetermined linear pressure in the nip between the surface winding means and the paper reel as it increases in size.

Abstract: An apparatus for winding a web on a sleeve has a pair of winding shafts adapted to hold respective such sleeves and each pivotal into a winding position coaxial with a winding axis and into a takeoff position spaced therefrom. A contact roller around which the web passes presses the web radially toward the winding axis so that when a sleeve is in the winding position the contact roller presses the web against it. A cutter can sever the web when same extends from the contact roller to the takeoff position between the contact roller and the takeoff position and thereby produces a leading web end extending from between the contact roller and a sleeve in the winding position.

Abstract: A tape cartridge having a reel lock in the hub that is capable of releasing the reel at the same time the drive mechanism engages the hub while minimizing the vertical travel necessary to provide a robust lock. The cartridge includes a housing and a tape reel in the housing. A tape drive interface on the reel, usually a circular gear on the reel hub, is accessible to the drive mechanism on a tape drive through a hole in the bottom of the housing. An arm is mounted in the hub. The arm moves between a first position in which the arm engages the housing to prevent the reel from rotating in at least one direction, and a second position in which the arm does not engage the housing and the reel is free to rotate in both directions.
