In addition, although the cone 4 is rotated to feed out the bristle material 5A, the cone 4 is made freely rotatable, and the bristle material 5A is held between a pair of feed rollers (not shown), one of which is driven to rotate. By doing so, the bristle material 5A may be fed while being fed out from the cone 4, and in this case, the pair of feed rollers can be separated so that they come into contact only when feeding the bristle material 5A.

Further, the motor 198 for rotating the cone 4, the cylinder 172 and motor 187 of the hair pulling means 6, and the motor 214 of the cutter 3 are controlled by a control circuit (not shown) configured using a microswitch, a timer circuit, or a microcomputer. I'm trying to make it happen.

Next, the operation of the apparatus of this embodiment configured as described above will be explained.

The bristle supply means 9 returns the bristle extracting means 6 to the right end in FIG.
When the start switch (not shown) is turned on with both clamps 7.8 returned to the right side in the figure, that is, the position adjacent to the fixed clamp 7, and both clamps 7.8 open, the motor 198 is driven and the worm gear 200 and the wheel gear 197 engage with each other. The plurality of cones 4 rotate at the same speed via the rotating shaft 194, and the long bristle materials 5A wound around the cones 4 are guided along the guide hole 192 of the guide body 2 and the bristle material guide portion 204 as shown in FIG. When the end of the bristles 5A is fed out to the left and does not reach the position inserted between the movable clamp piece 180 of the movable clamp 8 and the clamp receiver 183, the motor 198 stops.6 Then the motor 187 of the movable clamp 8 stops. The movable clamp piece 1 is driven through the arm 189 and the link 185.
The movable clamp piece 180 and the clamp receiver 183 clamp and grip the end of the bristle material 5A by rotating downward about the pivot 182 as a fulcrum. Thereafter, the cylinder 172 of the hair pulling means 6 is actuated to extend the piston 173 and the movable clamp 8 is slid along the guide rail 167 to the left end side in FIG. The bristle material 5A is pulled out to a predetermined length, and the manufacturing method 15 in FIG.
The motor 187 of the fixed clamp 7 located on the right end side of the manufacturing method 15 in FIG.
is driven, and the fixed clamp piece 181 is rotated downward about the pivot portion 182 via the arm 189 and the link 185, and the fixed clamp piece 181 and the clamp receiver 183 are moved to a position a predetermined distance from the end of the bristle material 5A. Clamp and fix.

Also, the motor 214 of the cutter 3 is driven, and the arms 213 . Vertical link 211. The movable blade 205 moves downward via the horizontal link 209, and the movable blade 205 and the fixed blade 206 cut the bristle material 5A, and then the cutter 3 returns to its original position. Both ends of the hair material 5 cut into a predetermined length by the cutter 3 in this manner are held and held by the fixed clamp 7 and the movable clamp 8. Further, the motor 67 provided on the mounting frame 58 of the upper conveyor 77 is driven, and the arm 69 rotates upward to pull up the right end side of the upper conveyor 77 shown in FIG. 3 via the link 70. As a result, the upper conveyor 77 is
It tilts diagonally upward while resisting the bias of the spring 66 using the shaft 59 at the left end in the figure as a fulcrum.

Meanwhile, the sewing machine 1 is operated and the main shaft 19 and the horizontal shaft 33 are rotated. The rotation of the horizontal shaft 33 rotates the cam plate 151 fixed to the horizontal shaft 33, and one rotation of the cam plate 151 causes the roller 154 to move along the cam groove 153.
The arm 155 rotates up and down using the pivot 157 as a fulcrum, and the side arm 159 reciprocates horizontally. That is, the third
In the figure, by moving the side arm 159 to the left, the mounting base 161 on which the hair material pulling means 6 is attached is attached to the sewing machine main body I.
Guide 162. toward the sewing part IB of A. It moves along the rail 163. As a result, the hair material 5 whose both ends are clamped and fixed between the fixed clamp 7 and the movable clamp 8 is supplied to the sewing part IB position, and then the motor 187 of both clamps 7.8
rotates in the opposite direction to the above, and the clamp pieces 180 and 181
The bristles 5 are rotated upward about the pivot 182 to open them.
is released, and as the cam plate 151 rotates, the hair pulling means 6 returns to its original position. At the same time, the motor 67 rotates in the opposite direction to rotate the upper conveyor 77 downward about the shaft 59 and is held horizontally by the restoring force of the spring 66. Here, the hair material 5 is connected to the belt 85 of the lower conveyor 86 and the upper conveyor 77.
It is held between the string belts 76.

Further, another cam plate 125 is fixed to the horizontal shaft 33, and the rotation of this cam plate 125 causes the link 130 to move to the pivot portion 1 through a roller 129 that moves along the cam groove 128.
It moves up and down using 31 as a fulcrum, and this is the connecting rod 133 and arm 1.
36 and 138, the mounting base 139 is moved diagonally upward from horizontal by moving a roller 142 which is not pivoted to the mounting piece 141 along the guide groove 145. The feeding claw 146, which is inclined and is provided on the mounting base 139, advances horizontally to the right and then moves diagonally upward to the right, as shown by the dashed line in FIG. In synchronization with this state, the aforementioned bristle supply means 9 operates to feed the plurality of bundles of bristle material 5 held between the fixed clamp 7 and the movable clamp 8 into the sewing section IB, which is then interlocked with the sewing operation described later. The blowing air 146 then moves diagonally downward to the left and horizontally moves to the left while catching the hair material 5 on the hook end 149 to further feed it into the sewing section IB. Further, the main shaft 19 is also rotating in synchronization with the horizontal shaft 33.
As described above, the feed table 39 to which the feed dog 30 is fixed moves in a substantially elliptical trajectory by the vertical feed rod 28 and the horizontal feed rod 29 that rotate via the eccentric ring 27 due to the rotation of the By driving the conveyors 77 and 86, the belt 85. When the bristle material 5 fed on the throat plate 16 while being held between the string belt 76 reaches the feed dog 30, the needle thread 11, the bobbin thread 13 and the clamping plate 49 are held between the feed dog 30 and the fixed presser foot 56. ．． The tape 17 guided through the guide tube 47 is sewn as shown in FIG. The upper and lower conveyors 7 are similarly driven intermittently while being pulled by 110.
Sent by 7,86. Above this, the lower conveyor 77,
86 and the tension roller 110 are driven by rotation of the horizontal shaft 33. That is, when the horizontal shaft 33 rotates once, the lower long arm 90 swings through the center-of-center cam 87 and the outer ring 88, which swings the arm 95 through the long hole 96 bolt 97 and rotates the roller ratchet 94 by a predetermined angle. move. This rotation of the roller ratchet 94 is transmitted to the intermediate shaft 91 via the ratchets 93 and 99, and from the intermediate shaft 91 to the toothed belt 102. It is transmitted to the lower conveyor 86 via the pulley 103, further transmitted to the upper conveyor 77 via the gear 104,
In this way, the upper and lower conveyors 77 and 86 intermittently feed the bristles 5 in small pitches while holding the bristles 5 between them.
5 rotates, and this is transmitted to the intermediate shaft 112 via the ratchets 114 and 120, and further, the lower tension roller 110 rotates intermittently via the toothed belt 123 and the pulley 124, resulting in the sewing shown in FIG. 2(A). The bristle rows thus prepared are stretched and fed through the culm while being held between the tension rollers 109 and 110 below the top 7, and the above operations are repeated.
