A mobile crane including a frame which, in its upper part, is provided with a main support structure and which, in its lower part and on opposite sides of the lower part of the frame, is provided with lower beam structures transverse to the main support structure, and upright legs between the main support structure and the lower beam structures; at least one wheel or wheel arrangement at both ends of the lower beam structures, i.e. in each lower corner of the crane; a trolley arranged to move along the main support structure and provided with a hoisting member; at least one hoisting mechanism; at least one rope drum arranged to be run by the hoisting mechanism; and at least one rope arranged from the rope drum of the hoisting mechanism to the hoisting member for running it, the rope drum being further provided with at least one hoisting rope connected to at least one counterweight.

The invention concerns a method and a device in a paper machine, coating machine, intermediate winder, unwind stand of a slitter-winder, or in any other device for treatment of a web. In the event of disturbance, the web (P) is made to be wound in a controlled way around at least one web guide roll ().

The invention concerns a method and a device in a paper machine, coating machine, intermediate winder, unwind stand of a slitter-winder, or in any other device for treatment of a web. In the event of disturbance, the web (P) is made to be wound in a controlled way around at least one web guide roll ( ).

Method and apparatus for guiding a web of paper or board or, alternatively, an edge strip sheared therefrom, in a paper machine or finishing equipment, the method being particularly suited for threading the web tail or edge strip through the machine in conjunction with a production shutdown or after a web break. According to the invention, the web ( ) or its tail sheared from the web so as to form an edge strip is supported electrically by means of taking surfaces or electrodes ( ) disposed on opposite sides of the web ( ) to different potentials. Particularly advantageously, the web ( ) or the edge strip can be adhered to a roll ( ), a belt ( ) or a wire by taking said support element to a lower potential and disposing a higher-potential electrode ( ) or a number of electrodes to the opposite side of the web.

Method and apparatus for guiding a web of paper or board web during manufacture

A method and device for reeling a paper or board web, wherein a first reel spool is in a reeling position in nip-defining relationship with a reeling cylinder and an empty second reel spool is placed in a stand-by position, the web is carried on a belt until it is reeled onto the first reel spool and the belt is guided in a run over the reeling cylinder and a guide roll, the first reel spool being transferred from the reeling position and pushed by the guide roll to a change position and the second reel spool is moved to the reeling position when the reel formed on the first reel spool is complete. The reeling of the web is transferred from the reel formed on the first reel spool to the second reel spool by cutting the entire width of the web by initially cutting a middle region of the web to form a tip and then extending the tip to side edges of the web, blowing the tip onto the second reel spool when the second reel spool is in the reeling position, and applying an adhesive proximate a rear edge of the web reeling onto the first reel spool in advance of a cut line separating the web reeling onto the first reel spool and the tip simultaneous with the cutting of the entire width of the web. The adhesive is applied at a uniform distance from the cut line so as to glue and fix the rear edge of the web to an underlying web portion of the web reeling onto the first reel spool.

Method and device for reeling a paper or board web

Method and device for finishing the surface layers of the machine reel

Splicing device for a continuous unwind stand

A method and device for reeling a paper or board web in a drum reel-up or equivalent, in which, when a paper or board reel formed on a reel spool situated in a reeling position becomes complete, a new reel spool is brought by transfer members into a stand-by position and accelerated up to the web speed. The reel spool with the complete reel is transferred into an exchange position apart from the reel drum and the new, initially accelerated reel spool is transferred into the reeling position. When the reel spool with its reel is transferred into the exchange position apart from the reel drum, the belt guide roll is transferred into nip-defining relationship with the complete reel that is being formed onto the reel spool and is displaced along with the reel spool into the exchange position so that the web runs during the entire exchange on support of the belt and through a nip between the guide roll and the reel spool. The device includes a reel drum, a reel spool whereby the web runs through the nip between the reel drum and the reel spool onto the reel spool, a transfer device for bringing a new reel spool into nip-defining relationship with the reel drum after the paper or board reel on the first reel spool has become complete, and means for transferring the belt guide roll together with the reel spool into the exchange position so that, during the entire exchange, the web is supported on the belt and runs through the nip between the guide roll and the reel spool.
