て真空ポンプの吸込口に効果的に導入される。 The cylinder 11 of the pasting roll 10 has a large number of suction holes 12 formed in its outer peripheral surface 13, and is in airtight contact with the outer peripheral flange of a fixed disk (not shown) attached to both ends of the cylinder 11. However, the structure is such that it is rotated by an external drive device (not shown). There is a hollow shaft 1 in the center of the fixed disks on both sides.
4 is attached in the form of a skewer, one end of which is closed, and the other end connected to the suction port side of the vacuum pump. Several outer cylinders 15 having spring seats are fixed to the outer periphery of the inner portions of both fixed disks of the hollow shaft 14, and an exhaust pipe 16 is loosely and airtightly fitted between the hollow shaft 14 and the outer cylinder 15. The suction hood 18 is located inside the cylinder 11 and has a box-like shape with a fan-shaped cross section that opens corresponding to a predetermined area for intake of air on the outer circumferential surface 13 of the cylinder 11. The exhaust pipe 16 is fixed to the bottom of the suction hood 18. It is connected. The opening end surface of the suction hood 18 is constantly pressed against the inner circumferential surface 19 of the cylinder 11 by the force of a coil spring 17 mounted on the outer periphery of the exhaust pipe 16. In this way, the cylinder 1 located within the predetermined area
The air sucked through the suction hole 12 of the vacuum pump passes through the suction hood 18, the exhaust pipe 16, and the hollow shaft 14, and is effectively introduced into the suction port of the vacuum pump.

どの成形装置に供給することもある。 The fiber layer 1 material unraveled from the reel 23 is continuously supplied to the cylinder outer peripheral surface 13 of the rotating adhesive roll 10 through an expander (not shown) or a heater 24 as required. On the other hand, the thermoplastic resin sheet 2 melted in the extruder 3 and extruded through the die 4 is continuously supplied onto the fiber layer 1 at approximately the same speed as the circumferential rotational speed of the cylinder 11, and both are polymerized. This polymerized sheet is
When the thermoplastic resin sheet 2, which is still in a softened state, rotates together with the cylinder 11 and reaches a predetermined area where the suction holes 12 in the cylinder outer circumferential surface 13 are effectively sucked, the thermoplastic resin sheet 2, which is still in a softened state, is compressed by the differential pressure caused by the intake air through the fiber layer 1. It is pressed against the upper surface of the fiber layer 1 and further penetrates between the fibers of the fiber layer 1. The polymerized sheet is then pressed between the adhesive roll 10 and the pressure roll 20 that is pressed against it with a constant force,
The laminate 5 is obtained by intertwining. This laminate 5
rotates together with the cylinder 11, and the suction hole 1
After passing through a predetermined area where 2 is effectively sucked, it is transferred to the circumferential surface of the cooling roll 21 and cooled. If the cooling is insufficient, further cooling is performed using another cooling roll 22 or other cooling means. The laminate 5 adhered in this manner is wound up and sent to the next process. Of course, the material may be directly supplied to a molding device such as a thermoforming machine without going through the cooling process described above.

The backing layer 6 heated in step 5 is supplied onto the circumferential surface of the pressure roll 20 as the roll 20 rotates, and is continuously polymerized on the free surface side of the thermoplastic resin sheet 2.

A backskin-like knit fabric made of 100% nylon yarn is used, and a low-density polyethylene homopolymer (melt flow index 10) is used as the thermoplastic resin sheet 2 material on the opposite side of the brushed side.
Thickness 0.15 mm from die 4 of extruder 3, resin temperature 200
The thermoplastic resin sheet 2 is extruded at ~220°C and polymerized on the adhesive roll 10, and the thermoplastic resin sheet 2 is adsorbed onto the outer circumferential surface 13 side of the cylinder 11 through the fiber layer 1. Furthermore, the backing layer 6 is made 15 times as thick as 3 mm. A foamed polyethylene foam sheet is fed onto the circumferential surface of the pressure roll 20 as the roll 20 rotates, and is continuously polymerized on the free surface side of the thermoplastic resin sheet 2. A laminate was obtained by pressure bonding at a pressure of 1.0 kg/cm. The peel strength between the nylon woven fabric and the polyethylene sheet of the laminate made based on the second invention is 6 kg/3 cm width, and the peel strength is 6 kg/3 cm width compared to the same material made with the conventional pasting roll without suction mechanism and the polyethylene sheet. The peel strength of the laminate under the same bonding conditions was 4 kg/3 cm width. In addition, local variations in peeling force were smaller in the former case than in the latter case.

に有効である。Effects of the Invention As explained above, the method for producing a laminate of the present invention uses a pasting roll in which air on the circumferential surface of a cylinder located within a predetermined area is discharged to the outside through suction holes, and Since the fiber layer and the thermoplastic resin sheet are integrated on the circumferential surface by the suction action and the pressure applied by the pressure roll, the thermoplastic resin sheet penetrates into the fiber layer and the peeling strength between the two is high. It is possible to continuously produce a laminate with little local variation in force. This is especially effective when the fiber layer is rough or uneven.
