  • Patent number: 9604789
    Abstract: Guide rail for an easy to clean conveyor, where the guide rail is adapted to have a straight position, in which position the guide rail is adapted to support a conveyor chain, and a folded position spaced apart from the straight position, where the guide rail comprises an upper support part adapted to glidingly support a conveyor chain, and a lower attachment part adapted to attach the guide rail to a holder, where the lower attachment part is adapted to allow the guide rail to pivot in the holder between the straight position and the folded position. In this way, a guide rail that allows for an easy cleaning of a conveyor is provided for. Such conveyors are e.g. used in the food industry.

  • Patent number: 6536330
    Abstract: An arrangement for a piston-and-cylinder unit is disclosed. The arrangement includes a cylinder member and a piston member movable therein, to which a piston rod is connected. The cylinder member includes a barrel pipe and closure portions at each end of the cylinder member, with the closure portion at one end exhibiting a bush. The bush is provided with a through bore for the piston rod and is enclosed by an end portion of the barrel pipe. The end portion is bent radially inwards, towards the piston rod and over a first circumferential surface of the bush. The bush is provided with a collar portion exhibiting an external second circumferential surface of the bush, enclosing the circumference of the piston rod and extending axially beyond the inwardly bent portion. The inwardly bent portion of the barrel pipe terminates in a circumferential edge located adjacent to a positive corner of the bush formed between the first circumferential surface and the second circumferential surface.

  • Patent number: 6047917
    Abstract: A reel-up in which paper is reeled up on reeling drums to form paper reels is provided. The reel-up comprises two stand members provided with stand rails to support the reeling drum. A secondary system consisting of first and second secondary units for receipt of new reeling drums is provided adjacent to the stand members. Each secondary unit comprises a first and a second secondary member, each arranged adjacent one of the stand members. Both secondary members of each secondary unit are arranged at the outer sides of the stand members so that the deleterious effects of paper dust, etc. between the stand members are eliminated.

  • Patent number: 5816528
    Abstract: A reel-up in which paper is reeled up on reeling drums to form paper reels, said reel-up having two parallel stand members; a surface winding mechanism in the form of a rotating surface winding drum and/or a belt to carry the web and deliver it to one of said reeling drums or a paper reel formed or being formed thereon; and a secondary system including first and second secondary units for alternate receipt of new reeling drums. Each secondary unit, includes an outer first secondary member and an inner second secondary member, each of the secondary members having a linearly movable secondary body, an actuator for moving the secondary body, and a press device to maintain a predetermined linear pressure in the nip between the surface winding means and the paper reel as it increases in size.
