    Abstract: Apparatus for transferring a web moving in a guided and supported web feeding course traversing around a rotary frame and passing therefrom to and winding as a web stock on a first core at a winding station proximal a rotary frame periphery is provided with a rotary circular cutter on the rotary frame that cuts the moving web crosswise of the web travel. Prior to cutting the web the first core is moved away from the winding station and replaced thereat with an empty takeup core. The rotary frame is then rotationally speeded up so that its periphery at which a frame carried web contact shoe and rotary cutter can be positioned move in tandem with the web. The web contact shoe can then be brought into contact with the web to hold it and the circular cutter is operated to cut the feeding web. A trailing end of a part of the web downstream of the cut continues on to windup on the first core. A leading end of the part of the web upstream remains held by the contact shoe. The contact shoe following web cutting is stroked outwardly slightly of the rotary frame periphery so that as the contact shoe passes proximal a periphery of the empty core, the leading end of the web contacts the empty core periphery and starts to wind on the core periphery, this thereby accomplishing transfer of the feeding web to the core winding operation.

    Abstract: A web rewind unit includes a turret with spaced spindles and cores for receiving the web. A slide is mounted on the turret beneath the web moving over the core at the winding station. A knife bracket is pivotally secured to the slide. A power cylinder positions the slide between a web cut position and a retracted position. A pivot unit connects between the knife bracket and the main cylinder unit. A pneumatic cylinder loads the pivot unit. A stop unit is mounted to the machine frame and includes an adjustable member for establishing angular orientation of the cutting knife to accurately locate the knife with respect to the web during the cutting action. An air bar is mounted above the web path and moves down through the web as the knife pivots. The free web end of the web moves into the new core. The air bar includes a cam which engages a cam roller on the bracket and pivots the knife to cut the web. The timing is preferably such that as the knife moves to the cutting position, the air bar cylinder is operated and the cam coupled to the knife bracket is engaged by the pivoting air bar and the knife blade pivots and moves through the web. The air bar moves through the web in a direction opposite the knife. The air blast drives the free end of the web downwardly into a guide about the new core.

    Abstract: A drive for a flying transfer winder wherein a continuously traveling web is transferred from a fully wound roll to a new core. A single winder drive motor is selectively connected to the winding cores and the motor speed is controlled by a dancer roll upstream of the winder. An auxiliary drive is provided to bring up the peripheral speed of the new core at the time of transfer to a speed which is somewhat less than the web speed. Drive means, including overrunning clutches, are provided in the winder drive and auxiliary drive to allow a smooth and controllable movement of the dancer roll during transfer of the web and transfer of control to the winder drive motor.

    Abstract: A method and apparatus for winding very lightweight web material e.g., paper, tissue and the like into coreless rolls which comprises the feeding of one or more continuous webs of the web material into juxtaposition whereby the juxtapositioned webs are transversely perforated or scored at spaced intervals to define easy tear lines and longitudinally split to sever the respective webs into a plurality of distinct lengths of connected sheets. The web thus scored and split is then fed along a feed path so that the juxtapositioned webs are separated and thereafter wound into coreless rolls on a winding mandril. The winding of the web material about the winding mandril is effected by securing the free end of the web to the winding mandril and thereafter rotating the mandril as the web is being fed. The web is wound into a roll about the mandril to a predetermined thickness and is then broken away from the continuous web along the adjacent score line as the material rolled about the mandril is removed. Thereafter the mandril is removed from the material roller thereon thus rendering the rolled material coreless. It is also contemplated that the web material after being slit and prior to winding on the mandril may be guided through a folding gauge in which the severed lengths are folded with one or more longitudinal folds prior to winding into a roll upon the mandril.

    Abstract: A winder for webs of sheet material utilizes a pair of drive motors of different, although slightly overlapping, speed ranges for driving the cores upon which the webs are wound. The motor having the higher speed range is connected to one end of the core by an air clutch and the motor having the lower speed range is connected to the opposite end of the core by an overrunning clutch. The first motor, therefore, drives a core at a steadily decreasing speed and increasing torque as the overall diameter of the roll being built on the core increases. When this speed decreases to the upper speed limit of the second motor, the overrunning clutch engages and allows the drive to be transferred to the second motor. This permits the building of significantly larger rolls than would be feasible with a single drive motor.

    Abstract translation: 用于片材卷材的卷绕机利用一对驱动马达，驱动马达具有不同的驱动马达，但驱动马达具有不同的速度范围，用于驱动卷绕卷筒的卷芯。 具有较高速度范围的电动机通过空气离合器连接到芯的一端，并且具有较低速度范围的电动机通过超速离合器连接到铁心的相对端。 因此，当建立在芯上的辊的总直径增加时，第一电动机以稳定降低的速度驱动芯体并且增加扭矩。 当该速度降低到第二马达的上限极限时，超越离合器接合并允许驱动器被传递到第二马达。 这允许构建比单个驱动电机可行的显着更大的辊。
