摘要:
A revolving door with a drive unit drivingly connected to a turnstile of the revolving door. The revolving door has at least one glass ceiling element. The drive unit is gearlessly constructed and has an electronically commutated multipole motor. The multipole motor is arranged at the glass ceiling element.
摘要:
A revolving door that has a drive, which is operatively connected to a turnstile of the revolving door and rotationally drives the turnstile. The drive includes a drive motor configured as a multipole electro-motor, the axis of rotation thereof extending parallel or coaxially to the axis of rotation of the turnstile and has a height of equal to or smaller than 80 mm.

In an apparatus for the fiber-sorting or fiber-selection of a fiber bundle comprising textile fibers, especially for combing, which is supplied by a supply device to a fiber-sorting device, especially a combing device, having clamping devices which clamp the fiber bundle at a distance from its free end, which is combed to remove non-clamped constituents, the clamping devices each comprise two clamping jaws. To increase productivity and to enable an improved combed sliver to be obtained, downstream of the supply device there are arranged at least two rotatably mounted rollers rotating rapidly without interruption, the clamping devices being spaced apart in the region of the periphery of the rollers, and the clamping jaws of the each clamping device are arranged to be movable in relation to one another and separately drivable.

To increase productivity and improve the combed sliver, the fibre-sorting device has at least two rotatably mounted rollers rotating rapidly without interruption, having the clamping devices and between the sliver-forming element and the drafting system the at least one fibre sliver is present in the form of a fibre structure having a width greater than its height, for example, following spreading by a web-spreader.
摘要:
In an apparatus for fibre-sorting or fibre-selection of a fibre bundle comprising textile fibres, especially for combing, the fibre bundle is supplied to a fibre-sorting device, clamping devices are provided, which clamp the fibre bundle at a distance from its free end, and mechanical device is present, which generates a combing action from the clamping site to the free end of the fibre bundle. To increase productivity in a simple manner and obtain an improved combed sliver downstream of the supply device there are at least two rotatably mounted rollers rotating rapidly without interruption, the combing device are associated with a said roller, and an arrangement for optimum feed and/or positioning of the fibre material to be combed is associated with the combing device.

In an apparatus for the fibre-sorting or fibre-selection of fibre material which is supplied by means of supply means to a fibre-sorting device, at least one mechanical device is present which generate a combing action to remove non-clamped constituents such as short fibres. To enable productivity to be substantially increased in a simple manner and an improved combed sliver to be obtained, downstream of the supply device there are arranged at least first and second rotatably mounted rollers with clamping devices for the fibre bundles, and the apparatus further comprises at least two supply devices and/or at least one further high-speed roller and/or at least two take-off devices.

摘要:
The invention relates to a protective coating for a mechanically stabile, in particular mineral and/or metallic base, comprising an inorganic polysilicate-cohesion adhesive layer which is uniformly distributed, essentially, on the base. A coating made of a glass film material having a thickness of less than 2 mm, preferably, less than 0.3 mm, is applied to the polysilicate cohesion adhesive layer prior to the hardening thereof, which covers the polysilicate-cohesion adhesive layer. According to the method for producing the protective coating, initially, the inorganic polysilicate-cohesion adhesive and the glass film material are prepared, then the cohesion adhesive is applied to the base which is to be coated and/or one side of the glass film material, and the glass film material is applied to the base which is to be coated prior to hardening of the polysilicate-cohesion adhesion layer, such that the glass film material covers the cohesion adhesion layer. Subsequently, the cohesion adhesion layer is hardened.
