Since the sub-pusher is shorter in the longitudinal direction than the pusher, it is less likely to be tilted by the resin pressure from the resin in the T-die, and wear and damage of the drive section can be suppressed. In addition, if a plurality of drive units are provided in one pusher without dividing the pusher, the pusher is likely to be tilted due to a shift in the operation timing of the drive units. As a result, the tilting of the pusher due to the deviation of the operation timing is also suppressed.

- a common pusher head 63a is provided for all pusher bars 63, but in this embodiment, each pusher bar 63 is provided with an individual pusher head 63a. This prevents the pusher base 62 from tilting due to the resin pressure.
- the drive unit 51 is provided for each sub-pusher 6, and the plurality of drive units 51 operate in conjunction to enable linear movement of the pusher 1 configured by the plurality of sub-pusher 6.
- the pusher 1 is composed of a plurality of sub-pusher 6 , and each sub-pusher 6 is provided with the drive section 51 . Since the sub-pusher 6 is shorter in the longitudinal direction than the pusher, the sub-pusher 6 is less likely to be tilted by the resin pressure from the resin in the T-die 28, and wear and damage of the driving portion 51 can be suppressed.
- the pusher 1 is likely to be tilted due to a shift in the operation timing of the drive units 51. , the inclination of the pusher 1 caused by the deviation of the operation timing is also suppressed.

- a plurality of (four in this embodiment) pusher bars 63 and receiving pieces 80 are arranged symmetrically with respect to the longitudinal center plane C of the die lip 28a. This makes it easy to uniformly apply pressure to the die lip 28a.
- the receiving piece 80 is provided with a housing recess 80a for housing the pusher head 63a.
- the bottom of the housing recess 80a has a shape substantially complementary to the tip of the pusher head 63a. More specifically, the tip of the pusher head 63a is curved, and the bottom of the accommodation recess 80a is similarly curved.
- the tip of the pusher head 63a and the bottom of the housing recess 80a are preferably curved in a cylindrical shape.
- the pusher head 63a is sandwiched between the upper wall 80b and the lower wall 80c inside the housing recess 80a. As a result, the pusher head 63a is stably held in the housing recess 80a without rattling in the vertical direction.
- the accommodation recess 80a widens toward the entrance side (pusher head 63a side) (that is, the length of the accommodation recess 80a in the vertical direction is longer), and the entrance of the accommodation recess 80a In the vicinity, the upper wall 80b and the lower wall 80c are not in contact with the pusher head 63a. This facilitates housing the pusher head 63a in the housing recess 80a.
- the receiving piece 80 is connected to a die lip piece 81 provided on the die lip 28a.
- the die lip piece 81 is formed by cutting out a substantially rectangular parallelepiped block to form a thin bending portion 81a, a receiving piece connecting portion 81b to which the receiving piece 80 is attached, and a fixing portion fixed to the main body of the T die 28. and a portion 81c. That is, the receiving piece connecting portion 81b and the fixed portion 81c are connected by the flexible portion 81a.
- An opening/closing structure W for opening and closing the slit of the die lip 28a indicated by the clearance amount S includes a receiving piece 80 and a die lip piece 81. As shown in FIG.
- the die lip 28a and the die lip piece 81 are sandwiched between a pair of side plates 75, and the slit of the die lip 28a opens and closes while being guided by the side plates 75. This enables stable opening and closing of the slit.
- the die lip opening/closing device 50 operates as follows. When the accumulator 24 and the T-die 28 are filled with molten resin, the slit of the die lip 28a must be closed. In this case, each drive unit 51 advances each sub-pusher 6 (linearly moves in the direction of the T die 28). When the pusher head 63a of the sub-pusher 6 moves forward, the pusher head 63a presses the receiving piece connecting portion 81b via the receiving piece 80, thereby bending the flexible portion 81a and causing the receiving piece connecting portion 81b to move toward the flexible portion 81a. centered on and rotates downward. Then, the gap amount S of the slit is reduced to zero. In other words, the die lip 28a is closed.
- each drive unit 51 causes each sub-pusher 6 to retreat.
- the pusher head 63a of the sub-pusher 6 retreats, the pressure of the receiving piece 80 by the pusher head 63a is released.
- the die lip 28a (slit) can be opened.
- the drive unit 51 was a direct-acting cylinder, but as in Patent Document 1, it has a motion conversion unit that changes the rotary motion of the drive shaft of the motor to the linear motion of the pusher. It may be a drive part of the form.
- each pusher bar 63 is provided with an individual pusher head 63a.
- the upper two pusher bars 63 in FIG. 2A may be provided with a common first pusher head and the lower two pusher bars 63 with a common second pusher head. In this case, the significance of configuring the pusher 1 with a plurality of sub-pusher 6 is hardly lost, and the number of parts can be reduced.
