ドナイフ3は研磨される。 By the way, the blade portion of the band knife 3 wears out as the fabric is cut. Therefore, in order to polish the band knife 3, a polishing device 12 is provided on the main body 1 below the table 2, as shown in FIG. 8 and the like. This polishing device 12 holds disc-shaped grindstones 15 and 16 that are rotatable around rotating shafts 13 and 14 that are inclined at a slight angle with respect to the running direction of the band knife 3 from above and below the band knife 3. By operating the operating handle 17, the two grindstones 15, 16 are integrally moved in the width direction of the band knife 3, and the screws 18, 1
9, the peripheral surfaces of the grindstones 15 and 16 are brought into contact with both sides of the band knife 3. That is, each time the band knife 3 is polished, the widthwise dimension becomes smaller, and the two whetstones 1 are reduced accordingly.
5 and 16 in the width direction of the band knife 3 and the need to bring the peripheral surfaces of the grindstones 15 and 16 into contact with the surface to be polished of the band knife 3, the operation handle 17 and the screw 18 are ,
Nineteen operations were required. Note that the whetstone 1
By rotating the band knife 3 with the whetstones 15 and 16 in contact with the band knife 3,
16 is rotated by frictional force with the band knife 3, and the band knife 3 is polished.

ようなつている。 In the figure, reference numeral 21 denotes a polishing device attached to the cutting device main body 23 for polishing the hand knife 22. This polishing device 21 is movable up and down inside the device main body 24 along a guide rod 25 facing vertically. A pair of upper and lower movable bodies 26, 27 provided in
and a cam 30 which is rotated by the operation of a handle 29 connected to a shaft 28 located between the upper and lower movable bodies 26 and 27 and protruding from one side of the device main body 24.
a spring 31 that urges the upper movable body 26 downward; a spring 32 that biases the lower movable body 27 upward; a grindstone mounting body 33 protruding toward the cutting device main body 23 side; and a grindstone mounting body 34 connected to the lower movable body 27 and projecting toward the cutting device main body 23 side on the other side of the device main body 24;
Disc-shaped grindstones 35 and 36 are rotatably attached to the tips of these grindstone mounts 33 and 34.
It consists of. For more details, please refer to the above-mentioned whetstone 3.
5 and 36 are pivotally supported by shafts 37 and 38 that are inclined in opposite directions to each other at a slight angle of inclination (equal to the angle of inclination of the blade portion of the band knife 22) with respect to the vertical line. The two grindstones 35 and 36 are configured to sandwich the blade of the band knife 22 in a plane from above and below at a position slightly shifted in the length direction of the band knife 22. Further, on one side of the device main body 24, there is a
The movable body 2 is pushed by the springs 31 and 32 so as not to apply excessive force from the two grindstones 35 and 36.
A stopper 39 is provided to stop the cams 6 and 27 from moving toward each other via the cam 30. Specifically, this stopper 39 is screwed into a female screw body 40 attached to one side of the device main body 24 and is provided so as to be movable up and down by rotation, and the tip of this stopper 39 is connected to the handle 2
By contacting the rod 29a of 9, the cam 30
The rotation of the movable bodies 26 and 27 can be stopped from moving toward each other.
なお、前記装置本体24は前記砥石35,36

7、延いては砥石35,36の開き状態を保持で
きる。 In the above configuration, when the band knife 22 is cutting the fabric on the table 43, the grindstones 35, 36 are movable by the cam 30 by lifting the handle 29 as shown by the two-dot chain line in FIG. 26 and 27 are separated from each other, so that they are separated from the band knife 22. At this time, the cam 30 is displaced from the oblique state shown by the solid line in FIG. 5 to the upright state, and the spring 31,
Since the cam 30 receives force from the movable bodies 26 and 27 on which the biasing force of the cam 32 is applied in the direction of pushing on the same line at right angles, the cam 30 does not fall down and pushes the movable bodies 26 and 2
7. As a result, the grindstones 35 and 36 can be kept open.

い。 As the band knife 22 becomes worn as it is used, it becomes necessary to polish the band knife 22. At that time, the angle of the handle 29 and the cam 30 is adjusted by the stopper 39 so that the grindstones 35 and 36 come into contact with the band knife 22 with an appropriate force, and thereby the movable bodies 26 and 27
The whetstones 35 and 36 abut against the cam 30 and are prevented from coming any further, and the whetstones 35 and 36 abut against the band knife 22 with an appropriate force. By rotating the band knife 22 in this state, the whetstones 35 and 36 are rotated by the abrasion force with the band knife 22 with their flat surfaces in contact with both sides of the blade of the band knife 22, whereby the band knife 22 is polished. be done. When the polishing is completed, the rotation of the band knife 22 is stopped, the cam 30 is rotated to its original state by the handle 29, the grindstones 35 and 36 are separated from the band knife 22, and the cutting operation is then restarted. .

なえる。 The width of the band knife 22 becomes smaller each time the band knife 22 is polished, but the grindstones 35 and 36 have shafts 37 that are inclined in opposite directions.
By being pivotally supported at 38 and in contact with the band knife 22 in a plane, even when the width of the band knife 22 becomes small, the grindstones 35 and 36 can be raised and lowered by operating the handle 29, and the band knife 2
All you have to do is move it closer to 2, making it very easy to operate.
