<p>1,148,546. Slicing machine. AMERICAN MACHINE & FOUNDRY CO. 13 Oct., 1967 [7 Nov., 1966], No. 46820/67. Heading A4C. A slicing machine, preferably for bread, comprises a drive roller 12 driven by a motor 26 and three idling rollers 14, 16 and 18 over which a plurality of band saw blades 20 are mounted to give two passes 22 and 24 of each band saw blade, each pass being fed through a blade guide assembly including two stationary blade guide members 32 and 34 for each pass of a band-saw blade, and four shafts 36, 38, 40 and 42 mounted in parallel spaced relationship with the rollers, upon which are rotatably and slidably mounted a plurality of annular blade guides 44 each having an annular recess 45 in the periphery thereof for receiving the band saw blades, said blade guides being interconnected by means of a plurality of rods 56 each of which are received into a recess, 58, in the adjacent guide means, each band saw blade passing through the annular recess 45 of one rotatable blade guide in each side of the slicing area and all the band saw passes travelling in one direction passing through rotatable blade guides mounted on one of the two shafts on each side of the slicing work area, and all the band saw passes travelling in the other direction passing through rotatable blade guides mounted on the other of the two shafts on either side of the slicing work area, alternate band saw passes travelling in opposite directions. The stationary guide means may be moved laterally when it is desired to alter the thickness of slices, hence causing the band saw blades to move laterally and the blades will pull their rotatable guides to their new position. The angle of inclination of the blades to the infeed direction is advantageously 36 degrees and there is normally a substantial clearance between the bottom of the blade and the bottom of slot 45, the teeth of the blade normally being above the slot.</p> |
