Definitions
- the main difiiculty encountered in producing fiber "flock or staple is that it is difiicult to obtain accurate cut fiber length since the arrangement of the individual yarn filaments within the bundle or tow are disturbed as the towapproaches the cutting area.
- the disturbance results from a turbulent air condition adjacent the cutting area created by the rapid rotation of the cutter head and ,blades affixed thereto.
- Such turbulence causes the filament ends adjacent the cutter to fan out, curl up, flutter andotherwise become disarranged.
- .It is therefore one object of my invention to provide a flock or fiber cutter which will cut yarn or fiber bundles in either dry or wet condition into accurate and filaments or fibers adjacent the cutting area is prevented.
- Figure 3 is a perspective partially in section of the aspirator unit which guides the fiber or continuous filament supply bundle to the cutting area and also urges the supply bundle firmly against the cutting edge of the stationary blade;
- the blast of air prevents the individual filament endsor fibers within the supply bundle from becoming disarranged adjacent the cutting blades because of air turbulence created by the rotating cutter head.
- the fan blades are canted and during rotation they create a suction which moves the air and cut fibers in an axial directionthrough the open spaces between the blades.
- a housing is positioned around the cutter head and a blower positioned therein behind the cutter head cooperates with the cutter head and the aspirator to create a suction within the housing in a direction away from the cutter head whereby the cut fibers are even more rapidly drawn away from the cutting area.
- the suction will help to prevent the filament ends or fibers within the supply bundle from becoming disarranged as they pass to the .cutting edge of the stationary blade.
- a preferred embodiment of my fiber cutter comprises a. rotatable propeller or fan type cutter head I
- the blades 15, 15 are canted as they extend from the hub whereby when the head 1 rotates, air and cut fibers or flock move in an axial direction through the open spaces between the blades 15', 15.
- the rim 16 stabilizes-the blades to minimize vibration thereof during rotation.
- Fiber cutting blades 17, 17 are mounted in the ribs 15,15 in a manner to be described hereinafter.
- the cutter head I and shaft 2 are enclosed in a suitable housing 19 formed of two separate pieces as shown in Figure 2 which overlap and snap into interlocking relationship as at 22, 22.
- the hood is supported by the supports 3 and 25.
- a supporting clamp 26 is afiixed to the bottom portion of one of the halves of the hood 19 and is adapted to be secured to the main support 4 by wing nut 29.
- An additional bafile plate 63 is provided which is fixed to the walls of the chamber 48 and extends downwardly through the channel formed by the plates 44 and 45 into the guide chamber at approximately a 30 angle to the bottom plate 43 of guide chamber 42.
- the plate 63 lies parallel with the plates 44' and 45 whereby two chan nels are actually formed which are in direct alignment with the exit of the bottom plate 43 of the guide chamber 42.
- the baffle plate 63 terminates in a vertically extending foot section 65 extending upwardly within the chamber 48.
- Compressed air is introduced into the chamber 48 through a flexible tube 66 and a rigid tube 67 which extends within the top portion of chamber 48.
- the air strikes the wall 68 of chamber 48 at approximately a 30 angle thereto.
- the chamber walls guide the air in a path (indicated by the arrows, Figure 3) down to and through the channels formed by the bafiies 44', 63 and 45'.
- the foot sections 45 and 65 of the bafiles guide the compressed air into the channels between the baffle plates 44', 45' and 63.
- the streams of air emerging from the channels between the baffle plates strike both the end of the bottom wall 43 at the exit end of the guide chamber 42 and the cutting edge of the stationary blade immediately adjacent thereto at approximately a 30 angle to the plane of the bottom wall 43 and the cutting edge of the stationary blade 33.
- the air blast is in the direction of travel assumed by the supply bundle over the cutting edge of the stationary blade 33.
- the aspirator unit B has several functions. It aids in feeding and guiding the fibers or filaments to the cutting edge of the stationary blade 33 and holds them down on the cutting edge of the stationary blade. In addition, it prevents the individual filament or fiber ends of the supply bundle adjacent the cutting blades from being disarranged by the turbulent air as created by rotation of the cutter head 1.
- the entire aspirator assembly A is affixed to plate 69 which, in turn, is supported by a Y bracket 69' atfixed to support 36.
- the supply bundle is under control at all times whereby uniformity and accuracy of fiber length is achieved throughout the cutting operation.
- FIG. 4 illustrates the manner in which the rotating blades 17, 17 are mounted on the cutter head 1.
- an elongated slot 30 is cut into the back portion of the rib 15' and extends partially therethrough to form a shoulder 82.
- a second elongated slot 84- in alignment with the slot 80 is cut into the front portion of the rib 15 and extends into the slot 80.
- a cutting blade 17 in the form of a wedge shaped tool bit is positioned within the second slot 84.
- a wedge shaped plug 87 is also positioned within the second slot and cooperates with the bit 17 to firmly hold the bit 17 in place within the second slot 84.
- the plug 87 terminates in a threaded portion or screw 89 which extends upwardly into the slot 80 through a removable plate 93.
- a washer 94 and a lock nut 95 fit over the free end of the shaft 89.
- the lock nut 95 is then tightened to draw the plug 87 upwardly into the second slot 84 to wedge it tightly against the blade 17 to firmly hold the blade in place.
- the blade 17 may have several threaded portions or screws 89 with additional lock nuts 95. With such an arrangement, shuttering or oscillation of the blade is prevented regardless of the R. P. M. of the cutter head 1. By adjusting the position of the blade 17 within the slot 84 the length of the cut fibers or flock may be accurately controlled.
- a fiber cutter according to claim 2 comprising an additional plate positioned between the angularly extending portions of the two top sections of the guide chamber which plate divides the channel formed therebetween into two channels.
