The invention relates to a method and to an apparatus for transporting a tail end (6) in a fiber web machine from one structural section to another in such a way that the apparatus comprises nozzles (8) for guiding the tail end (6) on the guide plate by means of an air flow (4). What is essential in the invention is that the blown air (2) is brought onto a guide plate (1) shaped into a curve in such a way that the air flow (4) of the blown air (2) guides the tail end (6) onto the curved guide plate (1) by means of a bump (3) functioning as an aerodynamic profile, i.e. a bulge guiding the air flow (4), formed in the curved guide plate (1). In addition, the invention relates to a use of a curved plate (1) for transporting a tail end (6) in a fiber web machine from one structural section to another.

A winding device for a web-shaped material has at least one first frame and at least one first roller holding device, with at least one roller holding assembly which can rotate about a first rotational axis. The winding has device at least one pressing element, and the at least one pressing element is arranged to be movable relative to the first frame in at least one adjustment direction and opposite that at least one adjustment direction. The at least one adjustment direction has at least one component which points towards the first rotational axis. A guide system for at least one drawing device, for drawing at least one material web, is arranged such that a first guide section of the guide system is arranged in a stationary manner relative to the at least one first frame. At least one linear connection between the at least one pressing element and the first rotational axis always intersects a second guide section of the guide system, regardless of the position of the at least one pressing element. A method for drawing a material web into a winding device is also provided.

Plant for the production of paper logs, including at least one unwinder that supports a reel from which corresponding ply of paper unwounds, at least one processing unit that is supplied with the ply and is configured to modify the structure or conformation of the same ply, guiding means for guiding the ply arranged along a predetermined path between the at least one unwinder and the processing unit. The guide means are configured to provide a nip traversed by the ply at a preliminary stage of drawing-in of the ply, the nip being subsequently eliminated when the step of drawing-in is completed.

This disclosure relates to a winding machine which has a plurality of equi-rotating rolls, at least two guide elements arranged mirror-wise, between which the sheets to be rolled up pass, with arched distal portions arranged in a mirror-like manner, the two guide elements being connected to a support configured to position in a mutually exclusive manner only one guide element at a time in the rolling space defined between the winding rollers. Moreover, the winding machine is equipped with a motor unit controlled so as to rotate the winding rollers in a direction or in the opposite direction depending on which of the two guide elements has its respective distal portion facing the rolling space.

A production method for a glass roll includes a start preparation step (S1) of feeding-out a first lead film (LF1) coupled to a starting end portion (GFa) of a first glass film (GF1) from an unwinding device (3) and allowing a winding device (8) to wind the first lead film (LF1 after passing of the first lead film (LF1) through a thermal film-forming device (4),). The start preparation step (S1) includes a temperature increasing step of causing the thermal film-forming device (4) to be increased in temperature to a film-forming temperature. The first glass film (GF1) reaches the thermal film-forming device (4) before the thermal film-forming device (4) is increased in temperature to the film-forming temperature.

A web unwinding and splicing system includes a turret unwind having a turret arm with rotatable shafts at opposing ends thereof to unwind a running web of an expiring web material roll and unwind a waiting web of a new web material roll. A web splicing unit operable with the turret unwind includes a web deflection device that bumps the running web onto the waiting web to splice the running web with the waiting web and a cutting device that selectively severs the running web, thereby creating a leading portion of the running web that is spliced to the waiting web and a trailing portion of the running web that remains separate from the waiting web. A vacuum system is positioned proximate the running web to suction in the trailing portion of the running web left on the expiring web material roll.

Improved apparatus and methods of operating a turn up apparatus on a paper machine to improve the performance of a paper machine turn up process is presented. The apparatus may include a cross track with an internal slot for a paperband to move upon and affixed a surface that is proximate to the first internal slot. The first apron may lie across a surface above a location for the paperband and interact with the paperband when the paperband is pulled out of the apparatus during a turn-up operation. An apron tensioning device may provide an additional force against an edge of a surface of the apron. A curved track may hold the paperband at an angle to an axis of the cross track, and the paperband feeding device may advance the paperband during a portion of a turn-up operation.

Rewinder for the production of paper logs adapted to guide and transversely pre-cut a paper web along a predetermined path, adapted to wind a predetermined amount of the paper web on a core in a winding station, and including a threading mechanism for threading the web along said path. The threading mechanism includes a dragging unit provided to engage the web to drag it along the path with a predetermined feed direction and at least one dragging member to engage a respective flap of the web preceding the production of the logs. The dragging unit is located downstream of the winding station and is adapted to release the flap of the web from the dragging member, the release means being arranged downstream of the dragging so as to intercept the flap of the web and disengage it from the dragging while the web is fed.

The printer is a printer for printing on a label continuous body including a plurality of labels temporarily attached to a belt-like liner at predetermined intervals, the printer calculates the label pitch from the downstream end portion of a first label and the upstream end portion of the first label detected by a second detecting unit that detects an end portion of the label, if the calculated label pitch is smaller than a distance from a first detecting unit for identifying a printing start position of the label to a printing unit, the printer feeds the label continuous body to a printing start position of a second label based on the calculated label pitch.

A feeding apparatus includes a roll support unit configured to rotatably support a roll sheet which is a sheet wound into a roll form, a drive unit configured to rotate the roll sheet in a first rotation direction for feeding the sheet into a conveyance path and a second rotation direction, an abutment portion provided so as to be capable of abutting against an outer peripheral surface of the roll sheet at a first position, and a rotation member configured to abut against the outer peripheral surface at a second position. The rotation member at the second position does not rotate with the roll sheet when the roll sheet is rotated in the first rotation direction, and rotates with the roll sheet when the roll sheet is rotated in the second rotation direction.
