Abstract: An apparatus for use with a printing press including a tension regulator for maintaining a substantially constant tension level on a web of printing medium passing through the printing press. The printing press has at least one dancer roller, and the tension regulator includes an actuator associated with the dancer roller for maintaining a constant biasing force on the dancer roller. The tension regulator also includes a reservoir which communicates with a first chamber of the actuator to define a second chamber larger than the first chamber. The volume of the second chamber is large enough that changes thereto are negligible to the extent that a piston of the actuator is displaced. Therefore, the pressure within the second chamber remains constant which permits a constant biasing force to be applied to the piston regardless of the displacement of the piston.

Abstract: A continuous web of sheet material is fed through the nip of a first pair of driven pull rolls around a series of idler rollers and through the nip of a second pair of driven pull rolls. The pairs of pull rolls are selectively rotated to exert a desired tension on the web in a tension zone formed between the pairs of rolls. One pair of pull rolls operates as feed rolls to advance a preselected length of the web to a rotating cutter mechanism so that envelope blanks of a selected length are cut from the web for each revolution of the cutter mechanism. The feed rolls are operated by a servo-controlled motor responsive to an operator initiated signal to adjust the feed length without interrupting the feed of the web to the cutter mechanism. The second pair of pull rolls operates as tension rolls and is servo-motor controlled to maintain a preselected tension on the web fed to the cutter mechanism.

Abstract: The tension of a strip can be controlled with high responsiveness and high accuracy despite its drastic external variation by threading the strip (1) between a transportation roll (2) and a movable transportation roll (10) and moving the movable transportation roll (10). The movable transportation roll (10) is mounted on one end of an arm (11), which is mounted for a swing motion around a supporting shaft (12), a torque around the supporting shaft (12) is generated in the arm (11) by an arm driving motor (14) connected directly to the supporting shaft (12), thereby applying a tension to the strip (1). The angle of swing motion of the arm (11) is detected by an arm angle sensor (16), and the tension of the strip (1) is detected by a tension sensor (15). The torque to be generated in the arm (11) is corrected in accordance with the detected angle and tension, whereby the strip tension is controlled for a target tension.

Abstract: In a capstan driven tape transport, placing the tape into a "zero" tension condition before it engages the first of two tape speed metering capstans of the transport. "Zero" tape tension is a negligible tension relative to the tape tensions normally present in the drive, and substantially approaches a value of zero tension. "Zero" tape tension is attained by the tape passing from the tape supply over an auxiliary capstan located upstream from the first tape speed metering capstan, and the tape segment emerging from the auxiliary capstan is configured to hang in a very loose loop. The loop is maintained at "zero" tension by sensing the loop position either by a slight pressure differential in a vacuum column or by a very light arm resting on the loop, and the sense signal is used to servo the speed of the auxiliary capstan to maintain "zero" tension in the loop.
