Title: Price-labelling device and method for putting price labels onto a price-label carrier
Inventor: GASDA JOCHEN
IPC: G09F3/10
Filed: 1988-09-13
Abstract: In shops prices are frequently set out in an eye-catching manner on price-label carriers which are made for example from cardboard. To this end, the price-label carriers have hitherto been printed with the particular price, it not being possible to reuse a carrier of this kind for a different price, or insert systems are used which have to be sorted through when changing the price. The price-labelling device according to the invention uses adhesive slips of paper which are provided with an adhesive substance on at least two opposite edge regions and are held flat on the price-label carrier until they are removed again in a manner which does not leave a residue. The price-label carriers are not adversely affected by the adhesive slips of paper and so they can be reused virtually without limit whilst the adhesive slips of paper only cause minimal costs.

Title: Sandwich element
Inventor: DOLL FRIEDRICH
IPC: B62D33/04
Filed: 1988-11-08
Abstract: The invention relates to insulating sandwich elements for the construction of smooth-surfaced lorry walls. The latter, which generally comprise sandwich elements composed of two bordering panels and a foamed insulating layer lying in between, are prefabricated with the edge regions to the adjacent sandwich elements having no insulation. In this region, the bordering panels have two different profiled shapes which are designed in such a manner that the individual wall elements can be hooked positively into one another and, in addition, when individual panels are damaged they can be removed without removing the entire sandwich element and a new one can be inserted. The cavities produced in the region of the profile overlaps are subsequently filled with foam and thus form a composite construction without a thermal bridge.
