Abstract: A method for fastening wrapping sheets made of paper or cellulose in pulp-bale packaging, wherein a pulp bale is wrapped using a single-piece or two-part wrapping sheet made of paper or using a lower sheet and upper sheet made of cellulose. The method is characterized in that, at the location of overlap of the two paper or cellulose sheets, or at the end fold of the wrapping sheets made of cellulose or paper, one or more clip(s), including a decomposable material, not leaving behind any harmful components, as bale processing continues, is introduced into the bale. This makes it possible to avoid a costly binding machine or paper-strapping machine, and does away with the outlay required for disposing of the wire by the end user. A fastening device which includes a decomposable material which does not leave behind any harmful components, as bale processing continues is also disclosed.

Abstract: An accumulator device (1) for the tying wire of a tying machine used in pulp production has a drive (3) at the inlet to the accumulator device and another drive (7) at the outlet from the accumulator device. By means of the accumulator device (1) according to the invention and the two drives (3, 7), it is possible to store the entire length of wire required for one tying cycle temporarily and then to remove the wire from the accumulator for the tying cycle. In this way, a dynamic accumulator volume is created for the tying wire in the accumulator device (1).

Abstract: In order to simplify leftover wire (3) at the tying machines used in pulp production, a device is used that has an inlet guide (2) for the leftover wire (3) and a bending device (4) to bend the leftover wire running through continuously into a helical or spiral shape.

Abstract: A refiner for shredding pulps having refining surfaces provided on a rotor and a stator and which form a cylindrical or a conical refining gap. The refining gap is set by wedges which are mounted on the stator and rotor and can be moved against each other.

Abstract: A device for feeding a pulp suspension to a tissue machine includes a headbox having top and bottom lips defining a slice gap forming a free flow jet of the pulp suspension. The device also includes at least one eccentric shaft for setting the slice gap between a minimum and a maximum height. Each eccentric shaft is supported at several points over the machine width and is driven directly by a gear motor.

Abstract: The invention refers to a device for feeding a pulp suspension to a dewatering installation, particularly for a tissue machine. It is mainly characterized by one or several one-piece, wedge-shaped, steel lamella tip(s) being provided to separate the individual sectors in a two-layer or multi-layer headbox.

Abstract: Apparatus and method for the mechanical refining of high consistency lignocellulosic feed material in a frustroconical refining zone, by facilitating the backflow of steam generated in the refining zone through the upstream feed zone which, despite the backflow of steam, imparts outward force on the feed material sufficient for the material to enter the refining zone and pass therethrough, without blockage or flow interruption. This is accomplished by providing, immediately upstream of the frustroconical refining zone (46), a hybrid feed/grinding zone (104), which acts on the wood chips with relatively high refining intensity at low refining power, so as to reduce the size of the material and outwardly convey the material by centrifugal force into the frustroconical refining zone against the backflowing steam, but without generating steam in the hybrid zone.
