Abstract

1,066,379. Reclaiming scrap in sheet making processes. A. H. VAN RIPER. July 31, 1964, No. 30289/64. Heading B5A. In a sheet forming process, the selvedge bonds cut from the edges of the sheet are gathered together to form an integrated strip which is crimped and finally cut into uniformly sized chips, for reintroduction into the process. As shown in Fig. 1, a sheet 5 is extruded, by a ram extruder 10, over rolls 19 on to a wind-up roll 20, the selvedge edges being cut off by fixed cutters 22. The edges B are drawn over rollers G, passed through a trough 30 to form an integrated strip, and the strip thus formed crimped by cooperating rotating gears 32, 34. The crimped strip is cut into chips D by a rotating saw blade 36, the chips being intermingled with fresh chips and reintroduced into the extruder. The chipping mechanism (see Fig. 4, not shown) comprises a trough 30 having a tapering base (47), and converging side walls (46) the base having an arcuate delivering portion (48) to the nip of gears (2), (3), (4) each releasably mounted upon spindles (62), (64) respectively. The crimped strip is passed along a passage, defined by walls of blocks (91) and (92), to a rotating saw blade (see Fig. 8, not shown) driven by friction discs (101), (103). An alternative shape of the crimping gears is shown in Fig. 6 (not shown).
