Title: Apparatus for swaging the end of a tubular metal piece
Inventor: RECKSIEK EBERHARD DIPL-ING
IPC: B21D41/04
Filed: 1984-06-21
Granted: 1986-02-06
Abstract: The invention relates to an apparatus for swaging the end of a tubular metal workpiece, in particular for forming the tubular neck of a steel flask or for producing pipe bends, having a clamping head for the metal workpiece, which can be displaced in the direction of the axis of the metal workpiece, and with a rotatable driven forming-roller holder with rotatably mounted rollers. In order to simplify the apparatus and, at the same time, to achieve greater degree of upsetting in the swaging region of the workpiece, it is proposed according to the invention that the forming-roller holder (1) accommodate at least two forming rollers (2) and that the forming rollers each consist of a plurality of essentially disc-shaped individual rollers placed one against the other. <IMAGE>

Title: Twisting machine
Inventor: IMHOF CHRISTIAN ING
IPC: D01H1/16
Filed: 1985-09-17
Granted: 1987-04-23
Abstract: Each rotating can (26) of the twisting machine is enclosed by a heat-insulating jacket (12). In the middle of the jacket height, a suction line for the air heated by friction during rotation opens into the interior (27) between the jacket (12) and the can (26). End limitations (6 or 8, 9) of the rotating can (26) and/or upper and lower closing parts (15, 17 or 5) of the jacket (12) are designed so that the pressures in the peripheral regions of the closing parts (16, 17 or 5) are at least approximately equal at the top and bottom.   These measures ensure optimum cooling with a minimum air quantity or air flow; thermal stress on the environment, that is to say the machine room or its air-conditioning system, by the heat generated is reduced. Furthermore, there is a possibility of utilizing the dissipated heat in an optimum manner, so that the net energy consumption is minimized. <IMAGE>

Title: Self-propelled pneumatic or hydraulic ram
Inventor: JENNE GUSTAV DR-ING
IPC: E21B7/26
Filed: 1986-03-06
Granted: 1987-09-24
Abstract: The subject matter of the invention is a self-propelled pneumatic or hydraulic ram with an essentially tubular housing 1 as well as a ram head 2 arranged at the front side of the housing 1 and having a front end face 3 and a circumferential surface 5 widening towards the rear, a percussion bolt which can reciprocate axially in the housing 1 between two stops transmitting its percussion energy to the ram head 2. So that reasonable advance of the ram is also possible at large bore diameters and so that the advance can also take place with little soil cover, it is proposed with the invention that the circumferential surface 5 of the ram head 2 be at least partly flattened in the longitudinal direction at opposite circumferential sides 6 relative to the circumferential sides 6', at right angles thereto, of the circumferential surface 5. In this arrangement, the tubular housing 1 can be additionally surrounded by a sleeve 8. <IMAGE>
Patent DE-3820718-C1 (DE)
IPC: B65H39/16
Filed: 1988-06-18
Granted: 1989-05-11
Abstract: The invention relates to a process and an apparatus for the production of an endless honeycomb band, consisting of flatly adjacent, partially bonded strips, which band can be drawn out by stretching in band longitudinal direction to form a honeycomb. Film sheets are continuously drawn off from a plurality of coils, provided on one side with equally spaced glue strips running mutually parallel in the sheet longitudinal direction and subsequently being laid one on top of another. The gluing is performed with a hotmelt adhesive, which is sprayed onto each film sheet in the form of a plurality of strips. The glue strips of the one film sheet are arranged offset with respect to the above-lying or below-lying film sheet by half a strip spacing in each case. The multi-ply film band is then treated for the intersetting of its individual plies by pressure and/or temperature and is finally divided transversely into sections of the desired width, which are stacked one on top of the other and pressed to form the endless honeycomb band. Film sheet sections of the same length are cut off, after the setting of its plies, from the end of the film band lying at the front in conveying direction, and are placed in layers one on top of another into intermediate stacks, which are pressed individually into packs. The packs are successively divided up into band sections, which are pressed to form the honeycomb band under the application of heat and subsequently cooled.
Patent DE-3841411-C1 (DE)
IPC: B41F23/04
Filed: 1988-12-08
Granted: 1990-07-26
Abstract: When washing the cylinders in a rotary press, there is a problem that cleaning liquid passes over the web of printed material running off into the drying route with an ignitable atmosphere. According to the invention, the cleaning of the cylinders takes place according to the specification of the measured gas/vapour concentration established in the dryer. At a value below the permissible gas concentration value, an amount of cleaning liquid can be added until the differential amount up to the permissible value has been used up. It is possible for the flow of the metered addition to be applied in partial quantities distributed virtually simultaneously over the washing bar, it also being possible for the web and print covering to be calculated. The permissible value can also be approximated by the fact that the moisture of the cleaning surface and/or of the web is controlled as an auxiliary measure. Via the correlation between the flow of metered addition and the gas concentration arising therefrom, automatic adaptation of the guiding system is possible so that complex safety tests are not necessary when a cylinder cleaning system is installed in a press with a dryer. The metered addition of cleaning liquid which is oriented by the threshold value reduces the duration of cleaning and saves wastage, it being possible, in particular, specifically to remain below the lower explosion threshold. <IMAGE>
