Abstract: A web winding up or unwinding device adapted for a web-form material coating machine comprises a web roll support, the web roll support comprising a web roll changing device, and a web edge guide device, the web edge guide device comprising a sensor device adapted for determining a shifting of a lateral edge of a web of the web-form material to be wound up on or unwound from the web roll arranged on the web roll support, a web roll support displacing device adapted for laterally displacing the web roll support, and a control device adapted for controlling the sensor device and the web roll support displacing device.

Abstract: The present disclosure relates to a device for sealing a chamber inlet or a chamber outlet for a flexible substrate, comprising a body having a sealing surface, a substrate opening formed in the body configured to be traversed by the flexible substrate, an elastic tube at least partially facing the sealing surface, wherein the elastic tube has a connecting portion for connecting to a gas supply and being adapted for inflating and deflating during operation.

Abstract: The invention relates to an evaporator device with a receptacle for holding material to be evaporated. With this evaporator device an oil film can be applied onto specific sites of a sheet to be coated, this sheet being coated with aluminum or zinc in a further step. At the sites at which the oil film is located, no aluminum or zinc is deposited. With the aid of a rod valve, precise application of the oil onto the sheet is ensured. This rod valve is driven by a stepping motor, which can release percentage fractions of oil vapor.

Abstract: The invention relates to an arrangement for changing a winding drum in a take-up or feed-out chamber of a coating installation for web-form material. One such arrangement can be provided on both sides of a coating chamber, the one arrangement serving as a take-up drum and the other arrangement as a feed-out drum. The arrangement comprises two tracks for receiving end bearings of a winding drum, the tracks being comprised of two parts, of which the one part is stationary and the other is pivotable. The arrangement is located in a housing with a door. If the winding drum is to be replaced, the door is opened and the pivotable parts of the tracks are folded outwardly such that they project from the housing. Onto the projecting track parts a winding drum can now be placed, it can subsequently be slid inwardly and be arrested.

Abstract: A tubular stroboscope is interposed in the line of sight between a viewing glass and a process to be viewed in a chamber. The stroboscope is rotated about a central axis transverse to the line of sight and has a pair of diametrically opposed slots parallel to said axis, one slot being substantially wider than the opposite slot. The stroboscope is preferably driven by a jet of inert gas acting on a drive wheel inside the chamber, aspiration means being provided for dust removal.

Abstract: A vacuum tank (1) in which a film is coated under high vacuum is divided by a partition wall (26) into a coating chamber (28) and a winding chamber (27) containing a supply roll (21) and a take-up roll (22). The coating chamber (28) contains an evaporator bank (24). Into the latter a coating cylinder (27) reaches. Diffusion pumps (14, 15) are connected exclusively to the coating chamber (28), so that the high vacuum necessary for the coating need be produced only in this coating chamber (28) and not in the entire vacuum tank (1). An inflatable gasket (32), variable in cross section, seals the partition wall (26) from the vacuum tank wall (1).

Abstract: A high-vacuum coating apparatus for coating films has beneath its coating cylinder (7) a pivoting unit (8) which can turn on a pivot shaft (25). It has an adjustable mask (29) and thereunder a shutter (28) which can run from a position covering an evaporator to a position releasing it. Due to its ability to turn, the pivoting unit (8) together with its parts can easily be cleaned.
