Abstract: An additive fabrication apparatus with an efficient reversal mechanism to reverse the orientation of foil guiding rollers is contemplated. To this end, according to an aspect, a foil guiding system comprising: a flexible foil guiding roller; and a bearing system arranged to bear said guiding roller, said bearing system comprised of end locking elements axially locking to the roller; a bearing arrangement defining a bearing position having the roller curved in bearing engagement. The bearing arrangement engages with an outer face of said roller in a manner so as to thereby flex the roller between at least two bearing positions in conformity with a rolling direction. The flexible roller in connection with the outside bearings replaces a fixed shaft arrangement of the prior art, which is easily tunable to the foil movement direction.

Abstract: The present invention relates to a mutant microbial host cell which has been modified, preferably in its genome, to result in a deficiency in the production of a polypeptide having ?-amylase activity AmyC or an homologous thereof. It has been surprisingly found that when the mutant microbial host cell according to the invention is used in a method to produce a compound of interest, for example an enzyme, an improved purity of the product is obtained.
