An unwinding device for rolls of paper or cardboard has a pair of stands which are movable toward and away form one another on release by motors which have sprockets engaging nontraveling chains fixed at their ends relative to the rails. The stands have bearing housings displaceable vertically thereon and carrying heads engaging in the roll and vertically shifted by piston-and-cylinder assembly in the plane of the uprights of the stand.

Unwinding apparatus for wound rolls

System for joining webs of material

A device for winding and unwinding a web of material and including two separated uprights, in each of which is mounted a horizontal chuck onto which the core tube can be introduced. To prevent the core tube from corrugating or tearing, there is a mechanism (15-17) that supports the reel (8) at the bottom during winding and unwinding and that can move along with the reel.

Device for winding and unwinding a web of material

A method of and device for attaching a web of material rolling off to a processing machine to the beginning of a fresh web that is wound on a reel. To provide a method that will inexpensively and rapidly ensure a reliable attachment between the two webs, the first web is separated upstream of a stored section with the processing machine turned off and the separated section at least partly reserved, the section of web with the second web is then forced into contact, and the end of the reserved web section attached to the beginning of the second web as it arrives by releasing the reserved web section with the processing machine in operation. The device comprises an upright with the replacement reel mounted on it, a mechanism for reserving a supply of web, and a mechanism for cutting the web. To provide a device for carrying out the method that will be simple in design and universally applicable, a transfer mechanism that accommodates at least part of a separated section of the first web and that can be forced into contact with the outer surface of the replacement reel is positioned between the cutting mechanism and a reservoir.

An apparatus for the unwinding of multiple webs which comprises an unwinding stand with bearing brackets for a plurality of web rolls and, preceding said stand, a storage medium for a plurality of web rolls, wherein the storage medium is preceded by an aligning apparatus which aligns each web roll with respect to its axial and angular positions and transfers it to a conveyor of the storage medium which carries it to the unwinding stand. The conveyor is provided with a plurality of holding cribs that are spaced apart the same distance as the bearing brackets and hold the web rolls transferred to them in their aligned position.

Apparatus for the multiple unwinding of webs

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 braking device for winding cores for webs of material to be unwound with varying web tension. The device includes a pressure medium actuated cylinder piston unit controlling brake shoes which act on the winding core trunnions. The cylinder-piston unit comprises at least two longitudinally aligned pistons having their axes coincident in the operating direction and abutting on each other in their rest positions. The pressure medium is applied to the pistons individually or in tandem to produce different braking forces.

Device for braking winding cores

A device for chucking tubular winding cores, and particularly cores carrying paper webs or webs of similar material, wherein chucking segments forming a cylindrical surfaces are radially positioned by means of a core trunnion having an equilateral polygonal cross section, each of the chucking segments bearing on an individual surface of the trunnion through a support member having a rounded profile and producing a line contact. The support members are carried without play or with very little play in a cage inserted coaxially to be freely rotatable between the chucking segments and the core trunnion.

Device for chucking tubular winding cores

An unwinding stand for a plurality of rolls of material has an elevating mechanism for raising the individual rolls of material to the level of bearing brackets mounted on stand columns and disposed on either side of the unwinding stand. The elevating mechanism includes a guide column disposed between the stand columns and an elevating platform with dual outriggers guided on the guide column for the loading of the bearing brackets disposed on both sides of the stand with rolls of material.

Unwinding stand for a plurality of rolls of material

An apparatus for rotatably mounting a web on a spool including two chucks, each carried by a shaft which is rotatably mounted in a mounting frame, and each having a mandrel axially delimited by a stop flange and on which the spool is releasably clamped. Each chuck has a stripping ring disposed around the mandrel between the stop flange and a spool to be received, and configured to be axially slidable therealong, and wherein the ring comprises an axially extending collar. An actuating device is mounted on the mounting frame and is coactive with the stripping ring to effect the axial displacement thereof away from the stop flange so as to strip the spool from the mandrel. The actuating device comprises a pressure member mounted for movement from a rest position to an operative position and having elements for grasping the collar of the ring at at least two points uniformly distributed over its periphery and pushing it away from the stop flange when in the operative position, and permitting the free rotation of the ring when in the rest position.

Chuck for webs of material wound onto spools

An apparatus for unwinding rolls of sheet material and for adhering the end of one roll to the beginning of the next at full running speed, without interruption. Means are also provided to permit operation with rolls of different widths and even with two narrow rolls alongside one another. A support which can be operatively positioned between two such narrow rolls can be moved laterally out of the way to take up an end-supporting position when a single wide roll is being unwound.

Unwinding apparatus for rolls of sheet material

A synchronizing system for synchronizing the speeds of two webs of goods, wherein the first web runs at a constant speed and the second web has an adjustable running speed. First pulses are generated which have a frequency dependent upon the speed of the second web and a first counter is associated with the second web and is triggered by the first pulses. The first counter is also controlled to be started and stopped by at least one pair of timing marks which are running with the second web of goods. As a result of the frequency of the first pulses and the starting and stopping of the first counter, the first counter reaches a constant count upon stopping and each time the first counter is started for the next count this constant count is reached. Second pulses having a constant frequency associated with the speed of the first web are used to trigger a second counter which is started and stopped by the first counter when the constant count is reached. The count that is finally obtained in the second counter is indicative of the amount of over synchronization or under synchronization of the speed of the second web relative to the first web.
