Embodiment Construction

[0032] Next, embodiments of the present invention will be specifically described. figure 1 is a schematic view showing a laminator having a coating device according to the first embodiment of the present invention, figure 2 is a schematic diagram of a coating device provided in the laminator.

[0033] This laminator 80 is a device for producing a laminated product by bonding sheet-shaped feed materials (web) as base materials to each other using a two-component curing type solventless adhesive. Specifically, the laminator 80 includes: a first conveying line 10 for conveying the first feed material 2 , a second conveying line 20 for conveying the second feed material 3 , and a second conveying line 20 for conveying the first feed material 3 . A third conveying line 30 of a laminated product 4 formed by bonding the feed material 2 and the second feed material 3 conveyed in the second conveying line 20 by an adhesive is arranged facing the first conveying line 10 and A die co...

Abstract

The invention provides a coating device. The coating device comprises a die coater (5) equipped in a way to face towards a conveying wire (10) for conveying feeding materials (2) and having a pair of slit-shaped outlets (6a, 6b) and a pair of inlets (7a, 7b) respectively communicated with the outlets; a first supplying part (40) supplying a first liquid (8) for forming adhesive to one (7a) of the inlets; and a second supplying part (60) supplying a second liquid (9) for forming adhesive by contacting with the first liquid to the other inlet (7b), wherein, the pair of outlets of the die coater is separately equipped along the feeding material conveying direction A of the conveying wire (10) and located adjacent to each other. The first liquid and the second liquid immediately contact with each other after discharged respectively from an outlet. Therefore, the coating device can easily perform preparation work and keep the coating face smooth when laminated products are manufactured through two-liquid solidifying type solvent-free adhesive.

Description

technical field [0001] The present invention relates to a coating device for producing a laminated product by bonding sheet-shaped feed materials (web) as base materials to each other using a two-component curing type solventless adhesive. Background technique [0002] Conventionally, a method of coating a solvent-free adhesive on a laminated feed material (laminate web) using a plurality of coating rolls has been proposed (for example, refer to Patent Document 1), and a method of using a first die coater ( die coater) coating the first component of the solvent-free adhesive on the film, and coating the second component of the solvent-free adhesive on the film with a second die coater to manufacture a composite film (for example, refer to Patent Document 2). [0003] In the method described in the above-mentioned Patent Document 1, such as Figure 8 As shown, two components constituting a two-liquid curing type solventless adhesive are supplied to the barrier (dam) 110, for...
