Method and device for applying expanses of glue on a strip of material forming the casing for articles in the form of a of the transformation of the tobacco industry.

摘要

In order to apply areas of glue 9B to a strip of material forming an envelope 12, the speed of rotation of the glue transfer cylinder is less than the speed of progression of the strip of material forming the envelope 12, and the areas of glue provided on the transfer cylinder have a length reduced in consequence with respect to the areas of glue 9B to be obtained on the strip of material forming the envelope, so that the areas of glue, thus protected against the risk of being ejected from the transfer cylinders, are withdrawn therefrom by a wiping movement, that is to say transferred, at the pre-established length L, to the strip of material forming the envelope.
