In a winding machine, the space defined by the support cylinders and the winding rolls is sealed and an overpressure is created in this space to relieve the force with which the winding rolls press against the support cylinders. For the purpose, in the area of the two lateral ends of the support cylinders sealing elements are arranged, which for adjustment to various web widths, are axially displaceable and at the same time can be moved away to an area outside the motion range of guide heads and their mounting. In the sealing position of the sealing elements, a fictional-look connection with the support cylinders is avoided.

System for joining webs of material

A drum-type winder for winding webs (5) of material, especially webs of paper, with two drums that the reels rest against while being wound. The winder has a freely rotating attenuating roller (12) that extends across the operating width, that can be applied more or less horizontally to the reels (4.1 & 4.2), and that can be forced away from the reels in opposition to an adjustable force.

Drum-type winder for winding webs of material

An apparatus for rolling or winding up a web of material with a driven supporting roll on which one or more winding rolls contact during the winding process and with a plurality of press rolls pressable on the circumference of one of the winding rolls which are mounted substantially parallel to the supporting roll axis on an end of at least one upwardly pivoting lever mounted laterally adjacent the supporting roll. The press roll pairs are each mounted on the end of a pivoting lever and their rotation axes are movable about one axis substantially parallel to the longitudinal direction of the pivoting lever. Advantageously the press roll pair is also supported movable about a third axis which is approximately perpendicular to the longitudinal shaft of the pivoting lever and extends perpendicular to the rotation axes. Also the pivoting lever can be variable in its length.

Apparatus for rolling up a web of material

A device for threading a web of flexible material through the array of rollers of a machine, e.g. a coiler for the web, utilizes an endless guide wire guided over deflection rolls integrated with those web-guide rolls which are located along the underside of the web. The wire-deflection rolls associated with the web-guide rolls along the upper surface of the web are spaced therefrom and have means cooperating with the kite wire attaching the leading end of the web to the guide wire for deflecting the kite wire off these deflecting rolls so that the deflecting rolls can be located centrally of the web-guide path.

Apparatus for treating a web of continuous material

The apparatus for automatically cutting and rolling up a sheet of material comprises a winder with a least one feed drum. The winder cuts the sheet of material, advantageously first the winder weakens the sheet of material along a cutting line. Then the sheet is cut through or severed by braking. The beginning of a new sheet formed by the cutting is attached to a new roll core by the winder after ejecting the finished rolled up roll and the beginning of the new sheet of material is held fixed during cutting by vacuum on the outer surface of the feed drum.

Method of and apparatus for the automatic winding of a web of sheet

In an apparatus for separate winding of longitudinally slit webs 4 and comprising a single support roll 5 and at least two rolls 6 for winding the slit webs, which web rolls have shafts 10 and ride on the support roll 5, the improvement which comprises positioning the web rolls 6 on the upper half of the circumference of the support roll 5 on alternate sides of a vertical plane 7 passing through the axis of said support roll 5, the apparatus including a cross-bar 11, a plurality of web-roll carriages 12 carried by said cross-bar 11 for longitudinal displacement thereon and adapted to be positioned in pairs to the width of the web strips to be wound and hence be aligned with the slits, and load-carrying means 8, 9 of adjustable force disposed on the web-roll carriages 12 and operatively connected with the web-roll shafts 10.

Apparatus for the separate winding of slit webs

In a machine for the centerless winding of webs (2), including support cylinders (3), a holder (4) for a core on which the web is to be wound, a motor-driven spindle (11) for the axial displacement of the core holder rotatably mounted on a shaft (5) displaceable in a guide (8), (9), and means for limiting the axial length of travel of the core holder, the improvement wherein said travel limiting means includes a control shaft (15) coupled with the drive motor (12) through a step-down gearing (14), (16), a slip coupling (18), (19), (20), trippers (23), (24), for limit switches (25), (26), associated with the drive motor, and a cam (21) in whose path an abutment (22) is disposed, the step-down gearing (14), (16), having such a ratio that no more than one full rotation of the control shaft (15) corresponds to the predetermined length of travel. Thereby even after resetting the winder to a web of different width there will still be the same limits on the axial length of travel of the core holder when replacing cores.

Core holder for a winder

A process for decelerating the drive of a web-winding apparatus including a yardage counter for the wound web and a speedometer for the web to be wound, comprising setting a computer for the nominal length of the web which computer, on the basis of the nominal length and of the instantaneous web speed, causes the drive to slow down to a standstill with a preset degree of deceleration; comparing said degree of deceleration with two different curves of which one would result in the nominal length of the web being undershot while the other would result in its being overshot if either curve alone were effective after deceleration has been initiated; and by means of the computer resetting the degree of deceleration on the basis of said two curves and switching from one to the other whenever the instantaneous degree of deceleration indicates the nominal length would be undershot or overshot.

System for decelerating the drive of a web-winding apparatus

In a web winding apparatus comprising a pair of spaced support rolls for a core tube to be placed thereon, means for driving at least one of said rolls, means for delivering a web to a core tube supported on said rolls, and means for cutting the web when it is desired to replace the core tube, the improvement wherein said cutting means comprises an elongated blade extending longitudinally of the rolls, and means for advancing and retracting said blade in the space between said rolls so as to contact and cut said web in advanced position and to withdraw said web into standby position between cuttings. The blade can be caused to move in a straight line or an arcuate path between active and inactive positions and guide means may be provided to prevent skewing.

Web-cutting apparatus

An unwinding apparatus for rolls of materials pivotably mounts the rolls with a pivot drive at each end of the roll. The torque of each pivot drive is equalized relative to the machine frame in each direction of rotation by providing for each pivot drive, a resiliently mounted lever which is fixed to the pivot drive and a contact member which is linked to the lever. Four switches are arranged in pairs symmetrically with respect to the contact member and are actuated thereby in response to movement of the lever resulting from torquing by the pivot drives.

Unwinding apparatus for rolls of material

A method and apparatus for the centerless winding of webs has a pressure cylinder which lies on a wind-up roll, both of which are mounted on vertical movement. The vertical movement of the carriage mounting the wind-up roll is modulated by coupling the vertical movement of the pressure cylinder therewith such that the carriages follow the movement of the pressure cylinder to a degree corresponding to the momentary degree to which the wind-up roll has been wound.

A broad drawing apparatus for moving webs of material comprises a roll having a plurality of individual roll sections mounted on shaft sections and a two part thrust bearing for determining the degree of curvature for the two adjacent shaft sections of every two adjacent roll sections. A ball and socket bearing for each shaft section is provided such that the ball and socket bearings of adjacent shaft sections are disposed side by side on opposite sides of the thrust bearing and wherein each thrust bearing part carries one of the adjacent ball and socket bearings.
