Comprising Rotary Pinch Pair Patents (Class 226/181)
  • Patent number: 9856100
    Abstract: A sheet guiding mechanism includes a pair of first rotators and a pair of second rotators provided in a conveying path for a sheet material, a first sheet guide portion, a second sheet guide portion, a shaft member, and a plurality of guide rollers. The first sheet guide portion and the second sheet guide portion form guide surfaces for the sheet material on both sides of the conveying path. Both end portions of the shaft member extending along a width direction are supported by the second sheet guide portion. The guide rollers are in contact with the sheet material conveyed in the conveying path, and rotate to follow the sheet material. The shaft member is bent by a pressure applied from the sheet material to the guide rollers when a tension is applied to the sheet material between the pair of first rotators and the pair of second rotators.

  • Patent number: 7870986
    Abstract: A lead-in roller clearance adjustment mechanism includes a pair of lead-in rollers for guiding a web with a clearance therebetween and a clearance adjustment mechanism for adjusting an amount of clearance. The lead-in roller clearance adjustment mechanism further includes motors for driving the clearance adjustment mechanism and potentiometers for detecting output positions of these motors, and adjusts the amount of clearance automatically. A clearance adjustment device includes a control device for an automated paper threading device and for clearance adjustment between the lead-in rollers, a web thickness of the web being inputted in the control device, the control device controlling the motors to set the amount of clearance at a predetermined value before threading the web into a lead-in roller unit, and to set the amount of clearance at a value corresponding to the inputted web thickness of the web after threading the web into the lead-in roller unit.

  • Patent number: 7765685
    Abstract: An apparatus and method are described for assembling and disassembling pipe. The device has a drive mechanism that be used to either assemble or disassemble pipe. The drive mechanism has two independent traction drives that can independently impart longitudinal forces on a pipe, either in the same or opposing directions. The drive unit can thus transport pipe or can facilitate the assembly of pipe from modular units or the disassembly of pipe into modular units. The method includes pulling or pushing pipe from the field from a fixed location with a traction device.

  • Patent number: 7615723
    Abstract: A drive roll release mechanism is rotatable about an axis of rotation and includes a drive roll carrier body having a carrier body sidewall adapted and configured to accept a drive roll thereon. The drive roll release mechanism further includes an actuator in sliding communication with the carrier body. A user depresses the actuator to correspondingly realize at least a partial release of a drive roll, which is removably mounted to the drive roll release mechanism, from the carrier body, enabling facile removal of the drive roll from the drive roll release mechanism.

  • Publication number: 20090120989
    Abstract: A material feeding apparatus has a vibration absorbing construction, in which an impulse and vibrations from a press apparatus, etc. are hard to transmit to a material feeding equipment, etc., and includes an inner housing that accommodates therein the material feeding equipment, and an outer housing connected to the inner housing through a vibration absorbing member. A vibration restricting member is provided between the housings to restrict the degree of freedom of vibrations, which are transmitted to the inner housing through the vibration absorbing member when an impulse force acts on the outer housing, only in a vertical direction. The vibration restricting member includes an upper plate member, upper and lower surfaces of which are interposed between a top wall of the outer housing and a top wall of the inner housing, and a lower plate member, upper and lower surfaces of which are interposed between a bottom wall of the outer housing and a bottom wall of the inner housing.

  • Patent number: 7383973
    Abstract: A wire feeding mechanism for advancing a continuous length of wire along a pathway includes a housing having two roller supports each rotatable about a corresponding axis transverse to a wire pathway. The roller supports are on opposite sides of the pathway and are driveably engaged with each other. A drive roller is on each of the roller supports for rotation therewith. The drive roller includes an outer surface extending circumferentially about the corresponding axis. The outer surface defines a groove having an included angle of less than ninety degrees (90°). The drive roller on each of the roller supports compressively contacts a continuous length of wire between the roller supports such that the wire is advanced along the pathway in response to rotation of the drive rollers.
