Abstract

Verfahren zum Vereinzeln von aufeinandergestapelten Blechen, welches sich auch für solche Bleche eignet, die zum Zwecke des Tiefziehens mit Lack beschichtet sind. Um ein einzelnes Blech von einem Blechstapel abnehmen zu können, wird die Temperatur eines Bereichs, der zwischen zwei Stel­ len liegt, an denen das abzunehmende Blech festgehalten wird, stark verändert, so daß sich das abzunehmende Blech verwirft und z.B. mittels eines Vakuumsaugers abgenommen werden kann. Eine Vorrichtung zur Durchführung dieses ver­ fahrens besitzt zu beiden Seiten eines Niederhalters, der gegen einen mittleren bereich des abzunehmenden Blechs gepresst wird, jeweils einen Gasbrenner sowie in den Ecken des abzunehmenden Blechs angreifende Vakuumsauger. Process for separating stacked ones Sheets, which is also suitable for sheets that are used for For thermoforming purposes are coated with varnish. To a to be able to remove a single sheet from a stack of sheets, is the temperature of a range between two digits len is to which the sheet to be removed is held is, greatly changed, so that the sheet to be removed discards and e.g. removed by means of a vacuum cup can be. A device for performing this ver driving has a hold-down device on both sides, the against a central area of the sheet to be removed is pressed, one gas burner each and in the corners of the suction cup attacking the sheet to be removed.
