A retractable and extendable support journal for engaging and supporting paper web winding tubes in a printing press utilizes a plurality of spaced radially extendable and retractable clamping strips to securely connect the winding tube to the support journals. Each clamping strip has one or more material compressing or compacting ribs which compact the material of the winding tube to insure an interlocking connection between the tube and the support journal.

An arrangement for the attachment of a paper web leading edge on a paper supply roll utilizes a rapidly setting material, such as a hot melt adhesive in the form of beads, drops or dots to attach the leading edge of the first paper web layer to the second layer. The drops or beads may bridge the junction of the leading edge with the second layer. Strings or threads, which are attached to the dots of the rapidly setting adhesive, may bridge the juncture.

An adhesive arrangement for a paper web supply roll acts as both a holding and a connecting adhesive during a flying roll change. A leading portion of a first layer of the paper web is provided with a plurality of apertures. A double sided adhesive strip is placed on the leading portion of the first web layer and partially or completely overlies these apertures. Those portions of the adhesive strip overlying the apertures contact the second paper web layer and act as a holding adhesive.

A paper supply roll leading edge securement, which is usable particularly during a flying roll change, utilizes an adhesive having sensor detectable constituents. This adhesive can be applied to or across the leading edge of the first layer of the paper web on the supply roll. The use of the sensor detectable constituents facilitates proper positioning of the paper supply roll and helps separate faulty products from the production stream.

A press-on roller which is usable to press a first paper web into contact with a second paper web includes a support tube and a resilient press-on sleeve which is concentric with the support tube and separated from it by an annular space. This annular space is provided with at least one and preferably with a plurality of gas-filled cells. These gas filled cells provide the press-on roller with a controllable resiliency.

A bidirectional pivot frame of a paper web changing device is supported for pivotal motion about a selected one of two pivot axes. The support for the pivot frame is accomplished by slidable locking supports that positively lock one set of pivot pins in place in guide slots in the side frames of the paper web changing device, while releasing a second set of guide pins. The slidable locking supports are shiftable to selectively positively lock the desired set of guide pins in place.

Method and apparatus for pivoting a bidirectional pivot frame

A roll support for a web fed rotary printing press supports a supply roll of a material web between clamping cones carried at free ends of support arm pairs. An array of strain gauges are attached either to the support arms or to a force measuring bushing for the clamping cones and are used to provide values indicative of the weight or bearing force of the supply roll. These values can be used to determine the amount of material remaining on the supply roll or to determine a weight imbalance in the supply roll.

Method for measuring forces in a supply roll

A device for connecting paper webs in a web-fed rotary printing press utilizes a pivotable support frame to move a paper web tension compensation device into a position against the paper web prior to a flying web splice. An upper roller on the compensation device applies pressure to the depleting web to adhere it to the new web while a lower roller on the compensation device moves away from the new paper roll to maintain the effective travel path of the depleting web constant so that the web's tension remains the same and the web does not elongate.

Device for connecting paper webs

A paper web supply assembly utilizes a pair of paper roll support arm assemblies to hold two paper rolls. Two gluing carriages are carried by side plates of the press and each of these carriages is movable toward and away from a receiving rod that supports a corresponding paper roll. The gluing carriage is used to position a paper web from a fresh paper roll to accomplish a flying web splice.
