Abstract: A coreless toilet paper roll is produced by winding toilet paper such that the winding speed in the winding apparatus is faster than the paper feeding speed in the paper feeding-and processing apparatus, during a beginning period and final period of the toilet paper winding step, by leaving the wound toilet paper roll in place, with the winding shaft leaves projecting radially outwardly for a pre-determined time after the winding step, and thereafter, by shrinking the leaves and removing the toilet paper roll from the winding shaft. The toilet paper roll so produced has a roll body made of a wound toilet paper material, wherein a beginning layer thereof is wound tightly, and subsequent turns of paper are gradually softened from a middle layer to an outermost layer, an aperture for receiving a supporting bar of a toilet paper holder formed through the center of the roll, and further, the inner surface of the aperture is smooth without projections.

Abstract: A sliver can which facilitates the location of a trailing end portion of the sliver. The sliver can includes a main body and a tubular member associated with the main body for receiving an end portion of the sliver. By positioning the end portion of the sliver in a specific area, i.e. the within tubular member, the end portion may be easily located.

Abstract: This invention relates to a filtration roving with the cross section of the roving exhibiting portions more tightly twisted than the remainder of the roving.

Abstract: A process and apparatus for accurately positioning and fixing a loom beam provided with side flanges for winding threads or fabric webs includes a pair of proximity switches which after the loom beam is brought into a prealigned position are positioned between the side flanges to determine the position of the loom beam and if necessary cause an adjustment thereof. The proximity switches are exactly symmetrically aligned with respect to a reference line that is the central line of a pressing cylinder which is provided to smooth the wound fabric webs or threads and extends between the side flanges. In case the proximity switches have different distances to the facing side flanges, the loom beam is realigned until the difference between the distances is compensated.

Abstract: A vertically-arranged rubbing finisher has a plurality of rubbing units each traversed vertically by a pair of slubbings which are directed to respective winding devices for winding on respective spools to form single-slubbing bobbins. The two winding devices receiving a respective pair of slubbings are disposed on opposite sides of a vertical, longitudinal plane of symmetry through the rubbing unit, the winding devices on each respective side forming a group including drive rollers for the respective spools arranged for rotation about a common horizontal axis. Each spool is pivotable away from its drive roller as its bobbin is formed on arms which, when the bobbin is completed, pivot further, downwardly, to deposit the bobbin on a conveyor belt for transfer from the machine before returning upwardly to collect a new, empty spool for filling from a supply device.

Abstract: In order to produce random changes in texture of pile fabrics, continuous multifilament bulked yarn is treated to detexturize spaced portions along its length.

Abstract: A device for withdrawing and gathering a fiber web discharged by a web delivering assembly of a carding machine includes a guide element arranged immediately downstream of the web delivering assembly and has a web guiding face; a support for positioning the guiding face to be movable towards and away from the web delivering assembly; an arrangement for urging the guiding face towards the web delivering assembly into a closed position with a predetermined force; a switch supported adjacent the guiding face for actuation by the guiding face upon movement of the guiding face away from the web delivering assembly in response to a web pressure opposing and exceeding the predetermined force; and an arrangement connected to the switch and responsive to the actuation thereof.

Abstract: In an apparatus for treating a blanket of rayon fibers with a treating solution having means for conveying said blanket and at least one means for compressing out excess solution prior to drying, including means along the edges of said blanket for causing the edges of said blanket to turn in and fold over on itself prior to compression during its advancement along the conveyor means.

Abstract: A device for withdrawing and gathering a fiber web discharged by a web delivering assembly includes a guide element arranged downstream of the web delivering assembly as viewed in the direction of web advance and a trumpet arranged downstream of the guide element. The guide element has an outlet opening through which the web leaves the guide element. The trumpet is positioned immediately at the outlet opening as the continuation thereof, so that the web can pass directly from the guide element into the trumpet.

Abstract: Self-twisted yarn is packaged on a take-up device to prevent loss or modification of the twist previously imparted to the yarn by maintaining the yarn in a substantially rotation-free state as it is guided onto the take-up device. This is accomplished by wrapping the yarn around an elongated guide rod as it is fed to the take-up device under tension or by controlling the tensioned free length of the yarn as it is guided onto the take-up device to preclude rotation of the nodes or points of twist reversal in the yarn.

Abstract: A method of processing a fibrous cable fed at a high speed comprises the steps of braking the cable by coiling it on a stationary cylinder and simultaneously discharging at a low speed the lower cable windings by exerting downward pressure on the upper windings. The discharged windings can be deposited into containers or cut into staple fibers by pressing the discharged windings against stationary knives. A device for carrying out the method comprises an upright rotatable shaft having a hollow upper part for receiving the cable, a downwardly projecting guiding member attached to and communicating with the hollow upper part, a stationary cylinder surrounding the lower portion of the shaft and having in its cylindrical wall a plurality of vertical slits, a wobble plate disposed within the cylinder and having a plurality of fingers projecting through the vertical slits in the cylindrical wall.

Abstract: A bobbin-changing device for a textile winding machine in which an elongate thread or strip of textile fibres such as spun yarn, sliver or roving is wound on successive bobbins, the device being for replacing a fully wound bobbin with an empty bobbin and including means for allowing the fully wound bobbin to drop down from its winding position and a frictional member which is engaged by the periphery of the fully wound bobbin at a position roughly diametrically opposed to the position at which the thread or strip reaches the periphery of the fully wound bobbin as the bobbin drops down from its winding position, for accelerating in the wind-on direction the position at which the thread or strip reaches the periphery of the fully wound bobbin and thereby breaking the thread or strip.

Abstract: In an automatic textile winding machine comprising a driving cylinder on which rests a slubbing bobbin for being driven thereby, a device for automatically forming an initial bight of a roving around the slubbing bobbin at the commencement of winding comprises a suction nozzle for receiving the leading end of the roving emerging from the nip between the driving cylinder and the bobbin and a reciprocating bight-forming finger which, in moving between a rest position and an operative position, engages the roving extending between said nip and said suction nozzle, and lays it around the bobbin, an air jet carried by the finger then serving to blow the leading end of the roving into the nip between the bobbin and the driving cylinder again.
