Abstract: A spool assembly configured to support a roll of material. The spool assembly comprises a first and second flange coupled together via a first and second arbor member. The first arbor member is slidably coupled within a first at least one slot of the first flange and slidably coupled within a second at least one slot of the second flange. A biasing member is coupled to the first arbor member such that the first arbor member is biased radially inward toward a longitudinal axis of the spool assembly. Rotation of the first flange relative to the second flange causes the first arbor member to translate within the first at least one slot and the second at least one slot causing a change in the arbor diameter.

Abstract: A shoulder assembly for mounting on a tire building drum is provided that includes a plurality of sections configured to interlock with another to form a shoulder ring to be mounted on a tire building drum when the tire building drum is in an expanded state, and a plurality of magnetic elements provided about a surface of the shoulder ring that is configured to contact a side of the tire building drum. The magnetic elements correspond to holding magnetic elements in the tire building drum. The shoulder ring is configured to maintain contact with the tire building drum during forming of a tire carcass, and the shoulder ring is configured to maintain its shape and stay with the formed tire carcass when the tire building drum is collapsed.

Abstract: A kit or set of components, which can be assembled, in a mix-and-match manner, to provide multiple, different despoolers, for different wire spool sizes. One particular kit or set has components to provide three unique despoolers; the kit has a shaft, a tension spring, a first shaft body, a second shaft body having a length different than the length of the first shaft body, and a tension lock. The components provide despoolers that are easy to install and easy to set-up, having a limited number of components, and that are easy to use.

Abstract: A coiler for producing tighter or smaller coils of dunnage uses a cam to move fork pins from a dunnage-receiving position inwardly to a more closely-spaced coiling position. The fork pins are coupled to pin mounts that cooperate with the cam and slots in a guide plate to move the parallel fork pins between the dunnage-receiving and coiling positions. The fork pins are mounted to extend perpendicular to and through the guide plate on opposing sides of a path of the dunnage to capture and wind a dunnage strip into a coil.

Abstract: A device for winding up a film at a packaging machine, the device including a reception mandrel drivable for rotation about a rotation axis and a reception sleeve for the film for being pushed onto the reception mandrel. The reception sleeve may be formed by segments arranged next to each other along a circumference or perimeter of the reception sleeve, wherein neighboring or adjacent segments may be pivotably connected to each other. The reception mandrel may be formed as rigid body having engagement structures that are configured to cooperate with shape features of an inner circumference or perimeter of the reception sleeve, when the reception sleeve has been pushed onto the reception mandrel, so that a rotation of the reception mandrel about the rotation axis causes the reception sleeve to rotate with the reception mandrel.

Abstract: A dispenser for rolled materials, including a first base, a second base rotatably engaged with the first base, the second base including a disc including a top surface having one or more ribs arranged thereon, and a vertical member connected to the top surface, a first post connected to the first base, and a second post connected to the first base, the second post including a flapper operatively arranged to engage the one or more ribs.

Abstract: Coreless rolls of tissue, such as rolls of bath tissue or paper towels, are produced by winding tissue logs on a mandrel having retractable pins. During winding, the pins extend and penetrate the first several windings of the log as it is initially wound, which prevents slippage. After the winding is complete, the pins retract to allow the tissue log to slide off of the mandrel for subsequent slitting into individual product rolls and packaging. The penetration of the pins into the first several windings of the log tends to mechanically entangle and structurally unify those windings to create a “soft core”. At the same time, the properties of the tissue sheets within the soft core are the same as the other sheets within the roll and are therefore usable by the consumer.

Abstract: A roll sheet supporting apparatus includes a pair of rotation shafts which are respectively fitted into end portions of the hollow portion of the core tube and configured to support the roll sheet rotatably and capable of being drawn out, an engaging member movable between a projecting position and a retracting position, wherein the engaging member projects from an outer circumferential surface of the each rotation shaft abutting on the core tube to engage with the core tube at the projecting position and retracts inward from the outer circumferential surface of the each rotation shaft at the retracting position, and an engaging member moving unit configured to move the engaging member between the projecting position and the retracting position.

Abstract: A mandrel for winding sheet metal has a generally tubular mandrel body extending along and centered on an axis and formed at one end with a plurality of radially throughgoing and angularly spaced apertures each having a pair of closed and axially confronting end faces, a spreading bar extending axially inside the body and having a respective pivot adjacent each of the apertures, respective rigid links extending through the apertures and having inner ends carried on the respective pivots and outer ends projecting outside the body, and respective segments outside the body and each pivoted on the outer end of a respective one of the links. Respective pressure plates are operatively connected at the one end between the segments and the mandrel body.
