<p>1321162 Cutter reel for cutting filaments LUMMUS INDUSTRIES Inc 5 Nov 1971 [14 June 1971] 51538/71 Heading D1F A cutter reel for use in fibre cutting apparatus in which the material to be cut, e.g. tow, is wound on the reel and pressed against blades by a roller 16, comprises a pair of circular frame members 12, 13 held axially spaced apart by connecting members, e.g. posts 14, axially aligned circular rows of radially directed slots 41, 42 in the frame members 12, 13 to receive blades 36 which span the space between the members 12, 13, a removable blade hold-down member 27 carried by the member 12 and having a groove 37 in its surface towards the blades, the groove 37 and blade 36 having cooperating inclined surfaces 37a, 36a, the other member 13 also having an inclined surface 38a which cooperates with an inclined surface 36a at the other end of the blade whereby the blade is urged into seating engagement, the surfaces of the frame members 12, 13 being undercut at 43, 44 to provide a space between the frame members which increases in volume, in the radially inwards direction, to facilitate radially inward movement of cut material for discharge from the reel. The member 12 comprises a central member 18 mounted on a rotating shaft 11, an outer annular member 24 connected to the member 18, and a central removable hold-down member 27 which snaps into engagement with the annular member 24. The member 13 comprises a central member 32 connected to an outer annular member 33. Each post 14 is provided with a longitudinal slot to receive the rear, non-cutting edge of the blade. For replacement of the blades, the member 27 is removed to expose the upper edges of the blades which may be removed axially. In an alternative embodiment, the blades are spaced radially outward of the posts, there being more blades than posts. The posts in this embodiment are preferably triangular in cross-section to prevent clogging of cut material passing into the reel. Selected blades may be positioned opposite the triangular shaped posts, the selected blades being of greater width to engage in longitudinal slots in the posts and to thereby act as guides for the cut fibre material.</p> |
