Abstract
An apparatus for the application of an adhesive film strip about the edge of a shaped part of sheet metal comprises a pair of application roller which rolls on the adhesive tape about the metal sheet edge, imparting to the strip a U-shaped cross section. The adhesive film strip is originally on a carrier tape and is on a storage reel from which it is drawn off by conveying rollers. After being separated from the carrier tape, the adhesive film strip is fed via free-wheeling pre-folding rollers to a pair of application rollers, and the carrier tape is removed by means of further conveying rollers. The pair of application rollers and the pre-folding rollers can be swivelled together about an axis extending parallel with the shafts of the application rollers, and are at the same time resiliently displaceable in the direction of this axis. The distance of the application roller shafts from the said swivelling axis is adjustable in order to achieve a leading or a trailing run. The pre-folding rollers have a longitudinal section of concave or V-shaped configuration, and each is supported by itself additionally by means of soft springs, the application rollers can follow the metal sheet e…
