摘要:
A silicon block is firmly connected to a carrier for being moved together for further working by sawing, cleaning or the like. The carrier consists of plastic, for example of glass-fibre-reinforced plastic, and has in its interior a number of continuous longitudinal channels. These longitudinal channels are sawn into, and so cleaning fluid can then be introduced into the intermediate space between the sawn-up wafers in order to flush out sawing remains.

In a method of separating wafers (12) from a vertical wafer stack (16), the wafers (12) are transported away individually from above via movement means (23). The movement means (23) include circulating belts (24), with a suction surface (25) against which the uppermost wafer (12) abuts, the abutment of the wafer against the suction surface (25) being enhanced by negative pressure. To separate a plurality of wafers (12) located one upon another, the movement means (23) are subjected to at least one of the following two steps: a) water (30) is forcefully jetted against the leading edge of the uppermost wafer (12), the water being directed obliquely from beneath the latter, or b) the movement means (23) guide the wafer (12) over a stripping device (32) which butts against the underside of the moving wafer and both forces the wafer against the suction surface (25) and generates a braking action thereon. Thereafter, the wafer (12) is moved to a transporting path (35, 37) to be transported for further processing.
摘要:
A method for coating flat structural parts (2), in particular furniture fronts, with a film (3), wherein the parts lie in a pallet (1) which is turned by about 180° in a rotator after the coating process, so that the coated parts (2) joined by a common film (3) can fall out of the pallet (1) and be separated. The essential point is that a pallet (1) which can be filled on two sides is used and that the previous turning back of the pallet after the part has been removed can be omitted.
