Abstract: The invention relates to a bellows, in the bellows body of which are provided supporting frames which are welded to the outer pleats of the bellows body. The connection between the outer pleats of the bellows body and the supporting frames is formed by a high-frequency welded joint. The bellows according to the invention can be produced in a particularly economical manner and, if required, the bellows body can also be coated with PVC if the supporting frames--as usual--are produced from rigid PVC.

Abstract: A telescopic cover element is made from a sheet material blank and has one U-shaped material deformation formed from multiple bends for receiving a rear portion wall/or providing an extension stop. A second U-shaped material deformation formed from multiple bends opens towards the exterior of the cover element to form a discharge channel.

Abstract: The invention relates to a shavings conveyor which has a continuously turning conveyor belt (1) provided with two lateral conveyor chains (2) as well as a housing (6) equipped with guide rails (8) for these conveyor chains, openings (11, 12) for the coolant to pass through being provided in the upper guide rails (8) of the conveyor chains. In this way a structurally simple conveyor is produced in which the delivered coolant can run off laterally in a reliable and quick manner through the region of the upper conveyor run (14).

Abstract: The invention relates to a scraper construction for telescopic steel covers comprising a metal carrier strip and an elastic scraper body. The cross-sectional configurations of the scraper body and the carrier strip are such that the latter is accommodated in a groove of the scraper body and the latter has retaining limbs that may be clamped between the carrier and a cover on which the carrier is secured.

Abstract: This invention relates to a shavings conveyor having a reversing contactor for protecting the drive assembly (1) of the shaving conveyor from undue wear caused by the overloading of the shavings conveyor. When the conveyor becomes overloaded, a torque support beam (12), which is attached to the housing of the drive assembly (1), is caused to rotate. A threaded rod (15) is attached at one end to the beam (12) and moves with the displacement of beam (12). An L-shaped chip (20), mounted to the opposite end of threaded rod (15) and having a control cam (21) attached thereon, is moved with the threaded rod (15) so that the control cam (21) attached thereto engages a control switch (22). As the control switch (22) is activated, it signals the motor of the drive assembly to briefly reverse the direction of movement of the shavings conveyor so as to disperse the accumulation of shavings.

Abstract: The wall elements (2, 2", etc.) of a cabin that is used to cover a machine include bends (2a, 2a'a) at their edges and the bends of adjacent wall elements are connected together by U-shaped connector bars (10, 10', 10") or bends (2a) and in some embodiments by sealing elements (9, 11a, 11b).

Abstract: The invention relates to a shavings conveyor, consisting of a hinged belt and two side plate chains, in which the rims of the hinged belt at the same time form the inner side plates of the two side plate chains and the height of these inner side plates is chosen so as to be greater than the height of the rollers of the side plate chains, so that a lateral definition of position of the shavings conveyor with respect to the stationary guide profile is produced in the lower and upper run of the hinged belt.

Abstract: The invention relates to a shavings conveyor in which the members of the hinged belt have on their edges running at right angles to the transport direction joint axis parts which extend over the entire width of the hinged belt and of which one is provided with a part-cylindrical outer surface and the other with a complementary part-cylindrical inner surface. Such a shavings conveyor is distinguished by particularly simple production of the hinged belt.

Abstract: The invention relates to an energy-conducting chain made from plastics material, in which the cross-pieces contain conical extensions and sprung stop tongues, in which the stop engagement can be released in a simple manner by means of a screwdriver and the individual elements can be reliably protected against damage caused by clumsy handling.

Abstract: The invention relates to a scraping arrangement for a telescopic cover, in which a buffer which is made from a different material from that of the scraper is arranged on the rear face of the scraping arrangement. With such a construction the choice of material for the individual elements can be thoroughly optimized.

Abstract: The invention relates to a telescopic cover (1) in which the individual cover boxes (2, 2', 2") comprise a top wall (3, 3', 3"), two side walls and a rear wall (4, 4', 4") and the extending movement of the cover boxes is limited by a stop (11). At least for connection of the rear wall (4) to the top wall (3) an elongated profile (9) is provided which has parallel flanges (11, 12) on one broad side between which the top wall is retained and of which the outer flange (11) at the same time forms the said stop, whilst the inner flange (12) at the same time forms an assembly stop for the rear wall (4). This results in a particularly quick and precise assembly of the individual cover boxes.

Abstract: The invention relates to a telescopic cover composed of multiple boxes in which three guide elements are provided for guiding two adjacent boxes in the region of each side wall, and of these at least one guide element extends over the length of the appertaining box by a specific dimension in the extended state of the two boxes and furthermore at least one of the three guide elements is releasable from the appertaining box. In this way a small compressed dimension of the telescopic cover can be produced even with very wide boxes and at the same time a self-supporting construction can be achieved in a simple manner which saves on material.

Abstract: The invention relates to a cabin-like cover, in particular for covering machines, in which the panels of the side walls have a U-shaped cross-section which is open towards the bottom and engages over a base frame so that the junction of the panels in the base frame is well protected against the entry of fluid and foreign bodies. In at least one side wall of the cabin-like cover a closure element is also provided and after it has been detached the individual panels of the side wall can be removed and thus later alterations to the side walls can be carried out without complete dismantling of the cabin-like cover.

Abstract: A power supply chain having a pair of parallel chain strands spaced by connecting webs provided with cross arms and separators defining openings for the accommodation of power lines. The cross arms, the separators, or both are adjustable to enable the sizes of the openings to be varied to fit power lines of different diameters.
