Disclosed is a feedstock device (1) to deliver film (2) to a bundle-wrapping machine and including, on the one hand, at least one reel (3) to receive a roll (4) of the film (2) to be delivered, and, on the other hand, a joining unit (5) to attach the next film (2) to the film (2) that is currently being fed. This device includes a support (6) on which the at least one reel (3) is mounted, with the support (6) being mobile in relation to the joining unit (5) to bring the delivered film (2) to the latter. The invention also has as its object a machine and a corresponding method.

The invention relates to a rolled up thin glass composite comprising a thin glass film and at least one further layer (10, 11, 20, 30) applied over the surface of one side of the thin glass film, wherein the at least one further layer (10, 11, 20, 30) is applied to a radially outer side of the rolled up thin glass film and the at least one further layer (10, 11, 20, 30) contains a desiccant which protects the thin glass film against stress corrosion cracking. The invention also relates to a method for storing a thin glass film by providing a thin glass film, applying at least one further layer (10, 11, 20, 30) over the surface of at least one side of the thin glass film, wherein a desiccant which protects the thin glass film against stress corrosion cracking is added to the at least one further layer (10, 11, 20, 30) and a thin glass composite composed of the thin glass film and the at least one further layer (10, 11, 20, 30) is rolled up in such a way that the at least one further layer (10, 11, 20, 30) is applied to a radially outer side of the rolled up thin glass film.

A method for cutting at least an outermost film of rollstock across a width direction of a film, the rollstock formed by a film sheet rolled from base end to tip end, the method including: separation step of generating a gap between the inner peripheral film and the outer layer by separating first edge portion of the outer layer from the inner peripheral film in a radial direction of the rollstock, in a state where the outer layer is remained to be rolled as a part of the rollstock; step of displacing a portion of the outer layer defining the gap in a first width direction from the first edge portion to second edge portion in the width direction; and step of cutting the outer layer across the width direction during the displacement step, while the first cutter is moved from the first edge portion to the second edge portion.

A guide film supply mechanism feeds a guide film toward a winding mechanism. The guide film is a film in which a pair of supports, which is long in the longitudinal direction of a base film and is thicker than a product film, is disposed on both side portions of the upper surface of the base film that is formed to have a width larger than the width of the product film. A product film supply mechanism feeds the product film toward the upper surface of the guide film. The winding mechanism forms a film roll by winding the product film for each guide film. The tension of the product film is set to be smaller than the tension of the guide film.

A bow spreader bar provides lateral stress on a web of plastic film as it travels past. An elongated arcuate bow member is supported on a rotatable support bar that can be rotated by a first actuator to adjust pitch angle of the bow member relative to the plane of the film. A second actuator mounted on a midportion of the rotatable bar has a rod connected to a center part of the arcuate member and adjusts the amount of bow or arc of the arcuate member. A remote control arrangement has a receiver coupled to the first and second actuators and a remote transmitter permitting an operator to control the pitch angle and amount of bow from a location remote from the film processing equipment.

A packaging machine packages items using film. The packaging machine includes: a film transporter for feeding film; and a cutting device for cutting film. The cutting device is transferrable by a driving force from a rest position into an extended position. The film is severable by the cutting device in the extended position. The cutting device is connected to a housing surrounding the cutting device via a return mechanism. The return mechanism is activatable upon the cutting device being transferred from the rest position into the extended position. A return force in a direction of the rest position is exertable by the return mechanism in the activated state on the cutting device in its extended position, the force being greater than a return resistance of the cutting device in its extended state by which the cutting device is held in the extended state without action of the driving force.

An apparatus (un-interleaver) for unwinding a roll of material interleaved with another material, and for separating the materials, includes a first platform, a second platform, a tension-sensor, an edge-sensor, and a controller. The controller monitors signals generated by the tension sensor and the edge sensor, and in response to the signals: a) causes the speed at which the second platform rotates to change to maintain a predetermined tension in the second material as the second material travels from the first platform toward the second platform, and b) causes the second platform to move relative to the first platform to align the edge of the second material traveling toward the roll of second material with the edge of the second material in the roll.

A method of plastic film coreless roll removal from a spindle, comprising pushing of the plastic film coreless roll from the spindle with a perforated wall, where pressurized air-water mixture is fed at pushing the roll, providing expansion of the inner diameter of the roll. The object of the claimed technical solution is to provide technical results, consisting in reduction of power consumption by decrease of compressed air flow rate, with simultaneous increase of speed and safekeeping of the roll at its removal from the spindle by reduction of friction between the internal roll surface and the spindle surface.

An apparatus for conveying a web using an engagement cover comprising resilient looped pile engagement surface.

A winding machine (10) is disclosed comprising at least one reel holder (12) mounted on a supporting frame (11) and rotatable around its own axis (13), and a plurality of reels (1-4) mounted on the holder (12) and integrally rotatable therewith so that at least one first reel (1) is in at least one operative winding position of a bobbin (5). It is further described a respective method for the in-line winding of bobbins (5) of stretch film (6), comprising the steps of rotating a core (7) on a reel (1) in an operative winding position to wind the film (6) onto the core (7), positioning a contact roll (15a) in at least one proximal contacting position in which it contacts the winding bobbin (5) for facilitating the peripheral winding of the stretch film (6) on the core (7), bringing the reel (1) from the operative winding position of the bobbin (5) to an operative unloading position of the bobbin, positioning an accompanying roll (15b) in at least one proximal contacting position in which it contacts the bobbin (5) for facilitating the peripheral winding of the stretch film (6) on the bobbin (7), transversally cutting the stretch film (6) and unloading the bobbin (5). The movement of the contact roll (15a) and the accompanying roll (15b) is carried out by means of electric actuators (18a, 18b).
