Abstract: A vertical winder for winding a web on a center wound roll has a fixed vertical frame (A) supporting a carriage for vertical movement thereon. The carriage has a vertically movable upright section (B) and a cantilevered section (C) positioning at least one elongated driven roll (D) above the center wound roll. A drive motor (E) mounted on the carriage drives the elongated drive roll, and a fluid-operated cylinder (F) positions the elongated carriage between lowered and raised positions during the build of a center wound roll. The method provides for delivering a web in open width at a central location to the center wound roll during driving and building of the center wound roll.

Abstract: A spread winder has a stationary support roll (A) in alignment with a moveable support roll (B) which is carried by a moveable frame (D) and which has a drive (E) operated to cause predetermined spreading as the size of the roll increases with suitable core guides (H) controlling the alignment of the core at all times during its horizontal transverse responsive to relative horizontal movement of the rolls during the build. An encoder (I) impresses a home position control on the drive (E) and a home position limit switch (J) provide proper support roll spacing at start up.

Abstract: The speeds of support rolls (A) and (B) of a surface winder are controlled during winding by sensing means including a movable roll (C) for detecting variations in web tension. The motors (F) and (G) are controlled responsive to the sensing means by motor control circuitry (H) and, through respective drives (D) and (E), independently drive the rolls (A) and (B).

Abstract: A loom cloth takeup having pivotally mounted arms A exerting a force upon a friction roll (F) has first and second control devices (E) and (H) respectively for controlling tension on the cloth ahead of the friction roll (F) and for controlling a motor (G) driving the friction roll (F) to afford full roll tension control during the build of the cloth roll. A regenerative DC motor drive (H) is provided to avoid slippage between the friction roll and the cloth during winding, and a center wind motor control utilizing a capacitor (I) in series with the motor imparts a negative slope to the speed load characteristic.

Abstract: A web tension control apparatus and method utilizes a control for a drive motor (A) including an oscillating roll (B) for moving a cam (C) in relation to a proximity sensor (E) for controlling the tension in the moving web being transported for takeup. The power output of the proximity sensor is transmitted for controlling the output of a motor by control circuit (D) for maintaining the tension in the moving web within desirable limits.

Abstract: A doffing mechanism wherein a cloth roll doffer (C) is normally carried in aligned laterally spaced relation to the cloth roll with a motor which are actuated by manually raising the cloth roll engaging means to forcefully move the cloth roll engaging means for doffing the full cloth roll into a cart positioned beside the takeup rolls for receiving and carrying away the cloth roll. A DC motor (E) drives the takeup, and a DC motor control has a bridge rectifier (F) in an armature circuit of the DC motor supplying full armature current to the motor during doffing.

Abstract: Apparatus and method for centering a web roll includes providing a support (A) for carrying the web roll in longitudinal alignment with a driven belt forming a cradle supporting the web roll for unwinding and winding the web. The support (A) includes a conveyor having a motor (C) producing relative transverse movement between the web roll and the driven belt in response to a signal from a detector (B) in a direction toward centering the web roll in respect to the driven belt. A second detector (D) is movable in and out together with the first detector for sensing the other edge of the fabric for discontinuing the relative transverse movement. The support (A) includes a conveyor and a lift and tilt mechanism for placing the web roll upon a table preparatory to moving same onto the cradle for unwinding.

Abstract: An oscillatable web guide roll and method of winding uses a cylindrical roll (A) with as recess at one end for receiving a cylindrical cam (C) upon a shaft which forms part of a mounting (B) for the cylindrical roll so that a cam follower (D) fixed to the cylindrical roll may be positively guided by the cam to produce oscillatory movement of the cylindrical roll (A) thus oscillating the web along its longitudinal axis during the building of the web roll.

Abstract: A drive for a movable center wind takeup for web material has an upright support frame (A) which carries a motor driven power takeoff (B) which is drivingly engageable with the movable takeup. An articulated arm (C) is carried by the upright support and is extensible to achieve alignment between the power takeoff (B) for driving the takeup and a vertically adjustable device (D) including a lever arm for effecting vertical adjustment between the power takeoff (B) and the takeup.

Abstract: A web roll (A) is positioned on a winding apparatus which includes a belt (B). An electric drive motor (C) drives the belt (B) roll (A) during winding and unwinding of the web. An ultrasonic signaling device (D) directs a signal downwardly towards the web roll and receives a return signal indicative of the size of the web roll for controlling the operation of the electric drive motor which rotates the web roll in a clockwise or counterclockwise direction.

Abstract: A batcher has a brake (E) connected to the packing roll (B) for slowing the packing roll as during an unwinding phase to vary the packing ratio between the packing roll (B) and the drive roll (A). A drive mechanism (D) utilizes a single drive clutch for imparting a free wheeling action to the packing roll during unwinding so as to facilitate operation of the brake in effecting the proper packing ratio.

Abstract: Apparatus for feeding warp yarns to a weaving machine has a driven yarn tensioning roll (A) over which passes the warp yarn as it is pulled from a supply into the weaving machine. Thereafter, the warp yarn passes over a dancer roll (B) and a guide (C). A motor (D) drives the roll (A) for rotation responsive to oscillation of the dancer roll (B) resulting from yarn tension. Power operated apparatus (E) including fluid operated cylinders move the dancer roll and guide away from the yarn tensioning roll (A) to permit quick thread up of the weaving machine. By providing a second driven yarn tensioning roll and associated elements it is possible to more effectively mix warp yarns being fed into the weaving machine. A potentiometer (F) is driven by oscillation of the dancer roll for controlling the speed of the motor (D).
