摘要： PURPOSE:To save the amount of laminating on the rear surface by moving a correction bar for applying a curl to the paper before lamination in compliance with the fusion protruding thickness of a thermoplastic resin, and thereby changing the angle of embracing the paper. CONSTITUTION:While proceeding to a nipple roll 7 via pass rolls 2-6, sheet 1 is given a curl by correction bars 8, 9. These correction bars 8, 9 are moved up and down in accordance with the thickness of thermoplastic resin extruded in fusion from a T-die 11 while taking the form of film, to change the angle of the paper 1 being embraced theta, which will in turn change the amount of curling given. This embracing angle theta shall be so set that laminating on both sides of the paper by a certain specific thickness will eliminate precisely the curl of the paper 1. On a chill roll 12, the resin film is affixed to the paper 1 with the above-mentioned nip roll 7. This arrangement provides saving of the amount of thermoplastic resin, which has been used in an increased amount for the purpose of correcting the curl.

摘要： PURPOSE:To prevent the occurrence of oil fume and a faulty product due to said occurrence by enclosing the contact part of the end of the extruding port of the die extruding molten thermoplastic resin with the molten resin by the gas inert to molten resin. CONSTITUTION:A die 1 is exclosed by a shutting wall 5, and the gas inert to molten thermoplastic resin is introduced into the space 10 between the die 1 and the shutting wall 5 from a gas-introducing port 6. The contact part of the tip of the die lip with the molten thermoplastic resin extruded from said tip, exists in said space 10, and is enclosed by the gas inert to the molten thermoplastic resin. As the inert gas, nitrogen gas is preferable for the reason of cost and safety. As the molten thermoplastic resin, polyethylene, polypropylene, ethylene-alpha-olefin copolymer, ethylene-vinylester copolymer, ethylene-alpha,beta-unsaturated carboxylic acid copolymer and metallic neutralized material, etc., are used.

摘要： PURPOSE:To restrict neck-in phenomenon and improve the quality as well as the production efficiency of a product by a method wherein the surface temperature of the end of a thermoplastic resin film, which contacts with a deckle for regulating the extruding width of the film, is controlled. CONSTITUTION:The rims of a resin film 2, extruded from an extruding die 1, are held by a deckle 3, fixed to the extruding die 1 through a deckle holder 4 and bolts 6 and provided with a built-in heater, and the resin film 2 is pressed and cooled between a cooling roll 7 and a nip roll 8, then, is molded through a separating roll 9 and is discharged. The surface temperature of the deckle 3 with the built-in heater 5 depends upon the temperature of delivered resin and the thickness of a thermoplastic resin film to be molded, however, in case the temperature of the resin is 300 deg. and the thickness of the thermoplastic resin film to be molded is 20mum, for example, the surface temperature of the deckle 3 is kept within the temperature of 300-400 deg., for example. When an air cooling hole is provided at the tip end of the dickel and the temperature of the tip end of the resin film only is reduced slightly, a flow resistance with respect to neck-in may be increased and, as a result, the amount of neck-in may be reduced.

摘要： PURPOSE:To coat the reverse side of a single-coated web in high quality and production efficiency, by supporting the coated and still wet surface with gas pressure, and supplying the coating liquid to the reverse side of the web at the point just before contacting with a rotating bar which is in contact with the web with a lap angle of >=2.5 deg.. CONSTITUTION:A web 1 coated with a coating liquid 2a is supported by an air- cushion device 6 at the first coating side 4a, and the second coating liquid 2b is applied to the reverse side of the web with a bar 7 to form the second coating film 4b. The bar rotates to the same direction as the travelling direction of the web, and the lap angle between the bar and the web is >=2.5 deg., pref. >=5 deg.. The coating liquid 2b is supplied through a nozzle 9 of a bar-supporter 8 to a guide groove 11 between a barrier member 10 and the supporter 8, and applied to the web 1 with the rotating bar 7. The flow of the coating liquid 2b is controlled by the web 1 and the bar 7, and the desired amount of the liquid is applied to the web. The residual liquid forms a bank 12.

摘要： PURPOSE:To weaken the bonding strength between paper stock and resin covering layer and consequently facilitate the separation of the resin covering layer so as to facilitate the recovery and reuse of resin-covered paper by a method wherein the resin-covered paper is bought into contact with the steam of organic solvent under the condition that holes are bored in the resin covering layer so as to pass through the layer in order to reach the paper stock. CONSTITUTION:Resin-covered paper is used for waterproofing milk pack or the like by coveringly coating thermoplastic resin onto both the sides of paper stock. At the recovery and reuse of resin-covered paper, the separation between the paper stock and resin covering layer is necessary. In this case, firstly, the resin-covered paper 1.4 is fed between a vertically sliding type punching roll 10 so as to bore holes, which pass through the resin covering layer and reach the paper stock, in the resin covering layer. Next, by introducing the resin-covered paper 14 in an organic solvent tank 18, the steam 20 of organic solvent is brought into contact with the resin-covered paper 14 so as to weaken the bonding strength between the paper stock and the resin covering layer. In succession, by feeding the resin-covered paper 14 between a pair of separating blades 12 and 13 both the front and rear resin covering layers 17 and 15 are respectively separated from the paper stock 16.
