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.

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).

Abstract: An apparatus is illustrated for unwinding a web, such as cloth or paper, which utilizes a driven belt having a width in excess of the width of the web forming a cradle for a cloth roll and the like with adjusters for adjusting the path of travel of the belt including at least one oscillatable roll over which the belt passes and which is oscillated responsive to sensors sensing the position of the belt. A pair of downwardly and inwardly tapering guides are provided spaced opposite respective ends of a tubular core for maintaining proper position of the web roll carried thereby. A pair of downwardly and inwardly tapering guides are provided spaced opposite respective ends of a tubular core for maintaining proper position of the web roll carried thereby. The method contemplates doffing the core of the cloth roll by utilizing a vertically movable roll for tightening the belt while at the same time lowering one of a pair of spaced rolls supporting the cradle so.

Abstract: A coalescer filter is illustrated for removing material from a gas wherein a collection of liquid coalesced by passing a gaseous stream upwardly within a coalescing material packed in an upright cylindrical housing is facilitated by creating a pressure drop in a tube by venturi action and communicating the pressure drop to a canister. The use of a float valve is also illustrated for controlling the discharge of liquid collected in a sealed drainage canister receiving coalesced liquid from a lower portion of an upright column or housing containing coalescing material through which a gaseous stream is passed upwardly.

Abstract: The drawings illustrate an apparatus for housing articles between a ceiling and a roof, utilizing a switch means for actuating suitable electrically operated pivoting means for retracting the apparatus into the ceiling and lowering it from the ceiling.

Abstract: A cloth inspection stand is illustrated having a run of cloth on each side of the cloth takeup roll carried at an angle for ready inspection by one standing in the aisle on either side of the cloth roll takeup. The inspection stand makes provision for guiding a downward run of the cloth from the inspection area over a roll carried by pivoted arms for movement up and down to vary tension on the cloth.

Abstract: A batcher and the like is illustrated for utilizing torque control rather than speed control to vary the packing ratio of the rolls of a surface wound cloth roll. A phase shifting differential transmission is controlled by a condensor in series with the armature of a field wound D.C. motor in a drive between the rolls responsive to cloth tension to maintain such tension substantially constant.

Abstract: An overhead loom takeup is illustrated having a first downward run of cloth wherein the cloth is moved thence upwardly and over a guide roll prior to being moved generally longitudinally over compensator means to a surface wound roll positioned generally above the warp beam. Doffing means are provided overhead of the beams in the aisles between adjacent warp beams and include rail carried transport means.

Abstract: A loom is illustrated having an oscillating guide roll receiving cloth made on the loom for guiding same to the center wound takeup. Means are provided for oscillating the guide roll which includes a drive roll also driven by the cloth for driving mounting means for the guide roll at a speed differential in order to produce an oscillatory motion determined by the movement of the cloth.

Abstract: An on-loom take-up apparatus having increased cloth roll capacity is illustrated wherein means are provided for maintaining the loom supported in raised position while removing obstructions to the cloth roll as would limit the size of the cloth roll as would otherwise be permitted by the raising of the loom. A separate D.C. drive is provided and a constant torque control is provided for driving the take-up roll responsive to tension in the cloth through a positive drive arrangement.

Abstract: A weavers platform is illustrated wherein a smooth tubular roll is carried substantially along each of the sides of the platform and the like extending below a walkway portion for providing a smooth guide for sliding movement of the cloth beneath the platform for delivery from a loom to a cloth takeup positioned in front of the loom.

Abstract: An oscillating guide roll assembly is illustrated for use with a cloth winder in building a cloth roll in such a manner as to avoid registry of the selvage portions throughout the build of the cloth roll. The subject oscillating guide roll is especially useful in connection with looms such as Sulzer looms having thickened edge portions which result from inserted filling ends in the selvage area.

Abstract: A swatch remover for sampling a web such as fabric or cloth moving in open width from a loom to take-up mechanism is illustrated as having an upright transverse frame member which is pivoted outboard of the winder adjacent each end thereof, and which may be pivoted downwardly for facilitating the extending of a length of cloth for swatch removal and later rejoining as by sewing.

Abstract: A loom takeup apparatus is illustrated wherein cloth is fed directly from the loom to the takeup utilizing an oscillating roll which is slidably mounted for axial oscillation on the longitudinal axis of the roll for distributing the cloth so that the edge or selvage portions which are often thickened do not remain in register but rather build in such a fashion as to avoid excessively large end portions of the roll.

Abstract: An improved surface wind batcher and method of collecting material in roll form while maintaining positional stability of the roll during its rotation comprising a pair of rotatably driven parallel side-by-side spaced support rollers which support and peripherally drive a roll of web material fed thereto in continuous length form. The rollers are mounted in movable bearings operated by pneumatic pistons which are automatically actuated during roller and roll rotation to increase the distance between the support rollers and thereby ensure positional stability of the rotating roll on the support rollers. Upon completion of roll formation, the support rollers are actuated to automatically doff the roll of material therefrom and return them to initial closely spaced position for formation of another roll.

Abstract: A tension control mechanism for cloth delivered from the loom and the like to a cloth roll carried by take-up mechanism positioned in front of the loom is illustrated wherein a sensing device engages the cloth coming from the loom under relatively light tension for driving motor control means responsive to movement of the sensor imparted thereto by variation in cloth tension.

Abstract: A doffing mechanism is illustrated wherein a cloth roll engagable means is normally carried in aligned laterally spaced relation to the cloth roll with driving means which are actuated by manually raising the cloth roll engaging means to be driven by the take-up mechanism in a reverse direction to forcefully move the cloth roll engaging means for doffing the full cloth roll into a cart positioned beside the take-up rolls for receiving and carrying away the cloth roll.

Abstract: A batcher and the like is illustrated for utilizing torque control rather than speed control to vary the packing ratio of the rolls of a surface wound cloth roll. A phase shifting differential transmission is controlled by a condensor in series with the armature of a field wound D.C. motor in a drive between the rolls responsive to cloth tension to maintain such tension substantially constant.
