First, the first embodiment according to the present invention will be described with reference to FIGS. 1A to 6 in the accompanying drawings.

The waterproof sheet manufacturing apparatus according to the first embodiment is a device for manufacturing the waterproof sheet 30 by heat-sealing the synthetic resin sheet 20 and the nonwoven fabric 10, as shown in FIG. And the first and second pressure rollers 40A and 40B formed longer than the width of the waterproof sheet 30 and the first belt member 50 wound around the first and second pressure rollers 40A and 40B. The lower coupling portion (A) consisting of a third and the first and second pressure rollers (40A, 40B) are located on the upper side and installed to maintain a distance at a position corresponding to the first and second pressure rollers (40A, 40B) A second belt member 70 wound around the four pressing rollers 60A and 60B and the third and fourth pressing rollers 60A and 60B, and having a second pressing member 72 on the surface thereof; It consists of a synthetic resin sheet 20 and the heater member 80 for applying heat to the nonwoven fabric 10 is drawn between the 1,2 belt members (50, 70).

At this time, the first pressing roller 40A and the third pressing roller 60A are interlocked with each other by a gear, a chain, a belt, and the like, which are not shown. That is, it rotates in the mutually engaging direction.

In addition, at least one first pressing member 52 engaged with the second pressing member 72 may protrude from the surface of the first belt member 50 as illustrated in FIG. 1A. That is, the sheet manufacturing apparatus may be configured in a state in which the first pressurizing member 52 is not provided as shown in FIG. 1B, but in the present embodiment, both the first and second pressurizing members 52 and 72 are provided.

The first and second pressurizing members 52 and 72 engage and press the nonwoven fabric 10 and the synthetic resin sheet 20 drawn between the first and second belt members 50 and 70. At this time, since the nonwoven fabric 10 and the synthetic resin sheet 20 are heated by the heater member 80, when the first and second pressure members 52 and 72 are engaged with each other and pressurized, the pressure portion melts and melts.

Then, the first and second pressure members 52 and 72 continue to maintain their pressurized state, which is installed so that the first and second belt members 50 and 70 mesh with each other and rotate at the same speed. This is possible because the supporting members 90 are provided in the first and second belt members 50 and 70.

In this process, the nonwoven fabric 10 and the synthetic resin sheet 20 are thermally fused to each other and then cooled while passing between the first and second belt members 50 and 70 to be bonded to each other.

As such, the nonwoven fabric 10 is stably transported without forcing, and thermally fused with the synthetic resin sheet 20, and the pressurized state is maintained. Thus, thermal deformation of the waterproof sheet is prevented during welding, and smoothness of the waterproof sheet is maintained. The overall deformation is minimized.
