Roller for a winding machine

Pressure roller system for a winding machine

In a paper-winding machine a paper web passes at least partially around a support roller rotating about an axis and the web is wound up on a windup roll bearing radially on the support roller. The support roller comprises a rigid tubular core having a substantially cylindrical outer surface and an outer layer of material on the outer surface. The layer of material has a thickness between 5 mm and 12 mm (preferably 6 mm to 8 mm), the material is a low-friction elastomer (preferably a nitrile or polyurethane rubber), and the material has a Shore A hardness of between 65 and 80 (preferably 70 to 74).

Support roller for paper-winding machine

A paper-winding machine having a frame and supports for paper rolls carried by the frame and forming winding stations has a pair of overhead windup rollers supported on the members and flanking the rolls, and respective sound-absorbing curtains of flexible sheet material on the windup rollers and movable from positions hanging down therefrom and absorbing sound generated at the stations and positions wound up on the respective rollers.

Sound-dampened paper-winding machine

An apparatus for positioning the beginning of a web of material, especially paper, against the roll of a winder from below. The beginning of the web is conveyed up against an upright plate-shaped web-positioning mechanism by compressed air. The compressed air is emitted in an essentially laminar flow up along the surface of and essentially parallel with the surface of a baffle.

Guide head for heavy winding rolls

A method and device for coating a web (2) of material, especially a web of paper or cardboard, traveling over a backing roll (1) wherein coating is applied to the web is excess and reduced by a flow-control component (3), especially a doctor, to the desired thickness and wherein the flow-control component is secured to a beam (5) that extends over the operating width. The coating-thickness deviation from a straight line is determined over the operating width and employed as a parameter for controlling the heat emitted by a heater (16), especially heating strips, positioned on the side of the doctor beam facing away from the backing roller.

Method and device for coating webs of material, especially webs of paper

The apparatus for inserting a winding sleeve in a winding machine includes at least one supporting roll, at least two adjustable winder support pieces with spindles positioned opposite each other for receiving the winding sleeve and at least one sleeve gripper pivotable between a sleeve receiving position and a sleeve delivery position alignable axially with the spindles. The sleeve gripper can be mounted on a guide crosspiece above the supporting roll or alternatively pivotally and telescopably on a press roller mount or other crosspiece on one side of the supporting roll.

Apparatus for inserting a winding sleeve or core into a winding machine

In a device for coating a web of material that travels around a backing roller, the device having a coating chamber that opens toward the backing roller, that extends over the operating width, that has a slot demarcated at the web-intake end by an overflow plate for supplying liquid coating, and having a flow-control system at the downstream end, the improvement which comprises structures defining a coating-guide channel

Device for coating a web of material

To lift the leading end of a paper web upwardly into contact with the underside of a perforated support roll which draws the web by suction thereagainst, a bar, rod or wire forming an entrainer is lifted by a pair of strands controlled by a windlass to engage the entrainer in a crease at the leading end of the web, the entrainer passing over a pressing roller which can be displaced toward the support roller and is retractable therefrom.

Method of and apparatus for the feeding of a paper web to a roll-making

A device for lifting the leading end of a paper web to the underside of a support drum on which rolls can be formed from the paper web comprises a lifting device which has a suction box pivotal thereon about an axis parallel to the drum axis, so that as the suction box passes between the blades of a longitudinal slitter, it can assume a generally vertical orientation. The suction surface is elastically deformable against the underside of the drum.

Apparatus for applying a paper web to the underside of a roll-making drum

A device for measuring the winding hardness of a strip, especially a strip of paper, that has been wound into a reel. The device consists of a mechanism for extracting a slip that has been inserted tight between two coils of the reel of paper with one end extending out of the side of the reel and of a dynamometer that measures the force necessary to extract the slip over a certain distance. To allow winding hardness to be displayed directly rather than in the form of a graph, the slip-extracting mechanism operates at a constant extracting speed, a pulse generator that is supplied with the resulting force, or with a control signal derived from it, by the dynamometer supplies counting pulses to an up-down counter at a frequency that is proportional to the force, and the slip-extracting mechanism is connected to an odometer that, when it detects equal distances, switches the counter from up to down and stops it.
