Leader devices usable with roll media and an image forming system having an output member are disclosed. A leader device may include a leader member having a first end and a second end. The first end may attach to the output member of the image forming system. The leader device may also include an attachment means disposed on the second end of the image forming system for removably attaching the leader member to a leading edge of the roll media.

Method for applying glue on tubular cores for the production of logs of paper material, comprising the step of supplying in sequence more tubular cores (1) along a predetermined advancing direction (A) and the step of applying on each of said cores (1) a pre-determined amount of glue on a first point (P6) and on a second point (P7). The method further comprises a step of orienting the glue (G6) applied on the first point (P6) towards the second point (P7) and along said advancing direction (A), and orienting the glue (G7) applied on the second point (P7) towards the first point (P6) and along a direction opposite relative to said advancing direction (A).

A paper tape turn-up construct including a cover flap and a multi-bend structure to both protect an adhesive layer and to build an optimized elevated structure to present the adhesive layer during initiation of the paper web turn up process. Methods and apparatus to form the constructs and apply the constructs to paper production equipment are also included. The multi-bend paper turn up construct includes layers of adhesive and pulpable substrate with strategically located release materials, such as silicon that enhance a bridging of a gap between a rotating paper web and an empty spool surface.

An apparatus for dispensing an adhesive with paper covers to be used in a paper web turn-up operation. The resulting adhesive and paper cover construct is used in effecting the attachment of a paper web to an approaching spool. In some examples, the paper cover of the deposited adhesive may be affixed on two sides surrounding the deposited adhesive, in other examples a single attachment may be used. In some examples, the paper cover may be perforated to facilitate rupture of the paper and flow of adhesive. In some examples, perforations may enable the movement of adhesive through the paper.

A light reflective film roll may include a core main body formed in a cylindrical shape and having a length in a width direction of 1.2 m or more; a cushion layer formed by a foamed resin and provided on an outer surface of the core main body; and a light reflective film including a light reflective membrane, which has a reflection unit formed by alternately laminating a high refractive index layer and a low refractive index layer, a pressure sensitive adhesive layer at one outermost layer of the light reflective membrane, and a hard coat layer at the other outermost layer of the light reflective membrane. The light reflective film may be wound up on the outer surface of the cushion layer.

The present invention relates to a paper web processing apparatus featuring a transfer tape construct designed for efficient turn-up operations. The apparatus includes a carrier paper with a zone coating applied in longitudinal stripes, an adhesive layer laminated to the carrier paper, and a cover flap that protects the adhesive from environmental contaminants. The transfer tape construct is mounted on an empty web spool, and the zone coating comprises a silicone-based release material. The cover flap is engineered to open in response to centrifugal and aerodynamic forces during spool rotation, facilitating the separation of the adhesive layer into ribbons along the zone-coated areas. This configuration allows the cover flap to bridge a gap between the empty web spool and a paper web, ensuring a seamless transfer process. The apparatus is designed to enhance the reliability and efficiency of paper web processing, particularly in high-speed environments.

A family of paper tape turn-up constructs for accomplishing automated paper web turnup in paper processing. Methods and apparatus to form the constructs are described. Methods and Apparatus to apply the constructs to paper production equipment are also described. In some examples, the paper tape turn-up construct includes a cover flap to protect an adhesive layer during initiation of the paper web turn up process.

The disclosed subject matter provides a mandrel feeding device and a battery winder. The mandrel feeding device has a dispensing station, an adjusting station, an adhesive application station, a transferring unit, a dispensing unit, a feeding unit configured for gripping a mandrel on the transferring unit and transferring gripped mandrel to a winding mechanism.

A cover-flap transfer tape construct and associated applicators for paper web turn-up are disclosed. A zone-coated substrate carried on a linered web includes a top-side central web-grabbing adhesive band bounded by uncoated edge zones, and underside edge mounting adhesive bands separated by an uncoated middle zone. An applicator forms an out-of-plane raised profile across a central portion of the tape while maintaining planar side bands, using cooperating forming members (convex crest and complementary cavity) and manual or motorized feed. The formed length is cut to yield a discrete tape construct with the raised profile over the central adhesive and side bands aligned with mounting adhesives. The tape construct promotes reliable interception and transfer of a moving paper web during turn-up.
