  • Patent number: 7124671
    Abstract: In a web cutter where a blade is used to cut a continuous paper web into sheets, a tractor is used to move the web past the blade for cutting. The tractor operates in a start-and-stop cycle so that the web is temporarily stopped to allow the blade to lower and shear the web. The tractor accelerates in the next cycle to move another length of paper downstream from the blade. A high-speed cutter requires high acceleration of the tractor. This acceleration force causes the web to whip up uncontrollably, causing the web to break or wrinkle. To reduce the web breakage, a moving mechanism positioned upstream from the tractor and operate a second motion cycle is used to move the web toward the tractor such that a loop of paper is formed upstream of the tractor, thereby reducing the whipping action of the web.

  • Patent number: 6985789
    Abstract: Web tension in web material passing through a web transport system is determined in real time using position sensors coupled to driven rollers that define a beginning and an end of a tension zone. The position sensors on the rollers provide information related to the amount of strained web material that has been added and subtracted from the web material present in the tension zone. The amount of web material added to, subtracted from and present in the tension zone in a sample time period is then converted to an unstrained amount of web material that when combined provides an estimate for the present amount of unstrained web material present in the tension zone. Because the length of the tension zone is both fixed and known, the tension in the web material is determined from the present amount of unstrained web material in the tension zone.

    Abstract: A system and method for controlling the width of a web material supplied to a machine by adjusting the tension of the web material. An operator defines a target web width via an input device. The input device generates a reference signal representative of the target web width. A sensing device senses the width of the web material supplied to the machine and generates a feedback signal representative of the sensed width. A control circuit compares the feedback and reference signals and generates a tensioning signal as a function of the comparison. A tensioning device is responsive to tensioning signal for adjusting web tension.

  • Publication number: 20020108983
    Abstract: A method for dynamically controlling a driver of a nip roller in a web printing press includes controlling the speed of the driver in a tension-control mode during a phase of printing press operation and in a velocity-control mode during another phase of printing press operation. The controlling of the speed of the driver in the tension-control mode is based on the tension in the web upstream of the nip roller so as to maintain the tension at a desired tension value. The controlling of the speed of the driver in the velocity-control mode is based on a predetermined driver velocity ratio for maintaining the web tension. The tension-control mode may be employed during press start-up as the web accelerates to operating speed. The velocity-control mode may be used during printing operations of the press.
