A process and cross-cutter for the product of sandwich elements with overlapping strips

摘要

In the production of sandwich elements with overlapping strips from a strand (2) comprising at least one rigid outer layer (29) and a foam material core (28), during cutting the formation of a bun is avoided by performing a separating cut by a band saw (3) and an indentation cut by a circular saw (25). The cutting zone (9) of the band saw blade (4) can be turned through 180 DEG by a turning device (12), and a turning device (30) is provided for the circular saw (25). The band saw blade (4) cuts right through the strand (2), whereas the circular saw (25) is adjusted so that it severs the upper outer layer (27) and the foam material core (28) of the strand (2) so that the lower outer layer (29) remains as an overlapping strip.
