The present invention concerns a method for joining the ply of a reel of paper in depletion with the initial flap of a new reel, as well as an apparatus adapted for carrying out such a method. Thanks to the method according to the present invention, and to the apparatus suitable for carrying it out, the joining of the reels takes place without using gluing means, like for example the double-sided tape used in known methods, avoiding the relative drawbacks, the adhesion between the plies of the reels to be joined taking place by electrostatic attraction.

An improved winding apparatus and system for winding strips of web materials.

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 paper sheet folding device (sheet folding device) 160 includes a paper sheet folding unit 60 and a tray unit 110 that is provided on one side surface 161a of a device main body 161 and includes a lower discharge tray 121 on which a paper sheet S discharged through a lower discharge port 85 is loaded. The tray unit 110 is pivotable in an up-down direction about a pivotal shaft 111. A discharge drive mechanism 132 is disposed at a center portion of the tray unit 110 in a paper sheet width direction.

A belt-form body conveyor that conveys a belt-form body includes a plurality of non-contact guide portions over which portions of the belt-form body are wound, and that support the belt-form body in a non-contact manner, and a drive unit that, when viewed in a direction that is perpendicular to a surface of the belt-form body before the belt-form body is supplied to the plurality of non-contact guide portions, causes at least two non-contact guide portions out of the plurality of non-contact guide portions to rotate in the same direction and by the same angle.

A dunnage conversion machine for converting an expandable pre-slit sheet stock material into a relatively less dense dunnage product includes an improved expansion assembly that provides means for adjusting the spacing between axes of rotation of components through which the sheet stock material is drawn. The adjustability enables pre-slit sheet stock materials of differing thicknesses and/or having differing slit patterns to be fed through the expansion assembly with no or minimal compression of an expanded dunnage product, jamming in the conversion machine, bunching, and/or tearing of the pre-slit sheet stock material or expanded dunnage product resulting from expansion of the pre-slit sheet stock material.

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.

A dancer suspension assembly for use in a roll-to-roll printing system, which assembly comprises a wire element connectable to a dancer of the printing system, which wire element is connected to actuator via a spring element, which actuator is configured to control a spring force exerted by the spring element on the wire element, and a pulley assembly around which the wire element runs. The spring element allows the operator to adjust the spring force and to apply said spring force to the dancer at any position of the dancer. Both the web tension and the dancer position can be controlled in a simple manner.

Method and parameterization unit for parameterization of a tractive force controller of a controlled roller of a web-processing machine, the tractive force controller controlling a speed of the controlled roller in order to transport a material on the web-processing machine from the controlled roller to a further roller or from a further roller to the controlled roller at a line speed and while being subjected to the tractive force. The method includes, during a standstill test at a line speed of zero, increasing the tractive force to an identification tractive force, preferably 90% of a predetermined standstill tractive force operating point, to determine standstill system parameters of the tractive force system, to calculate standstill controller parameters of the tractive force controller from the standstill system parameters of the tractive force system, preferably by a frequency characteristic method, and to parameterize the tractive force controller using the standstill controller parameters.
