知られている。(Prior art) As a method of manufacturing a mat by bonding a rubber sheet to the back side of a carpet, an unvulcanized rubber sheet and a carpet are placed in advance on a smooth metal plate, and the metal plate is drawn into a press. A method is known in which the above-mentioned unvulcanized rubber sheets and carpets are heated under pressure. In addition, a sealed space is formed at the mating part of a pair of upper and lower molds, an unvulcanized rubber sheet and a carpet are stacked and mounted in this sealed space, and pressurized air is supplied to the sealed space to uncure the carpet. A method is known in which the above mold is heated while being pressed against a vulcanized rubber sheet to perform vulcanization and adhesion at the same time.

になつていた。(Problem to be Solved by the Invention) In the method of directly pressing an unvulcanized rubber sheet and carpet by sandwiching them between upper and lower heating plates, while the above-mentioned rubber sheet and carpet are firmly bonded, the pile of the carpet is The problem was that the carpet was pressurized by the heating plate and collapsed, and was heated and set in that collapsed state, resulting in a loss of cushioning properties and a poor appearance as a carpet. Even when the vulcanized carpet is placed in a napping machine, not only is sufficient nap not obtained, but the fibers of the pile are damaged and the number of steps increases.

た。 On the other hand, in the method of compressing a carpet to an unvulcanized rubber sheet using air pressure, if the base fabric of the carpet is breathable, the air pressure is balanced at the interface between the carpet and the unvulcanized rubber sheet, and therefore the necessary bonding is achieved. Pressure could not be obtained, the mold had to be changed depending on the height of the pile, and it was troublesome to attach the carpet and unvulcanized rubber sheet to the mold.

This makes it possible to easily adhere a carpet to a mold and, if necessary, to simultaneously adhere multiple sets of carpet and unvulcanized rubber sheets.

い。(Means for solving the problem) First, unvulcanized rubber sheets and carpet of a predetermined size are stacked on a belt conveyor, and the unvulcanized rubber sheets and carpet are placed in a press having heating plates on the top and bottom. Transfer to a lower heating plate with a smooth surface. The above-mentioned unvulcanized rubber sheet is a composition made of rubber such as natural rubber or synthetic rubber,
Its thickness is preferably 0.5 to 2.0 mm. Further, the carpet has cut pile or loop pile, and backing may be present or absent. The above-mentioned belt conveyor is made of a material that has excellent heat resistance, high thermal conductivity, no air permeability, and good release properties after vulcanization, such as a glass fiber fabric coated with fluororesin. A belt is preferred.

合、ダイヤフラムの上方空間を空気圧10〜100mm
Hgに減圧してダイヤフラムの垂れ下がりを防止
することが望ましい。 Next, the press is closed, and a diaphragm is placed on the belt conveyor above the lower heating platen, which is fixed to the upper heating platen of the press and has an open cavity on the lower surface and a diaphragm that divides the cavity into upper and lower halves. A mold equipped with a mold is brought into close contact to form a closed space surrounding the unvulcanized rubber sheet and the carpet on the belt conveyor. In this case, the air pressure in the space above the diaphragm is 10 to 100 mm.
It is desirable to reduce the pressure to Hg to prevent the diaphragm from sagging.

せる。 Next, the pressure in the space below the diaphragm of the mold is reduced to preferably 1 to 50 mmHg for 20 to 60 seconds, and then pressurized air is sent to the space above the diaphragm to push down the diaphragm. Press down at a pressure of 15 kg/cm 2 for 10 to 60 seconds to bring the carpet into close contact with the unvulcanized rubber sheet.

る。 After that, the pressure in the space above the diaphragm is reduced, pressurized air is introduced into the space below, and this pressurized air is used to directly press the carpet onto the unvulcanized rubber sheet at a pressure of preferably 2 to 10 kg/ cm2. The rubber sheet is then vulcanized for 3 to 20 minutes, preferably at a temperature of 120 to 180 DEG C., thereby adhering the rubber sheet to the back surface of the carpet.

ましくない。(Function) By closing the press to form a sealed space on the lower heating plate and pushing down the diaphragm, the back side of the carpet comes into close contact with the top surface of the unvulcanized rubber sheet.
The contact surfaces of the two become familiar. At this time, by reducing the pressure in the space below the diaphragm, the affinity between the carpet and the unvulcanized rubber sheet is further improved. In addition, since the diaphragm is pushed down without directly heating the mold, even if the carpet pile falls down, it will not be set to the fallen state by heat, and the next time the diaphragm is raised, Pile stands up. However, if the pressing down pressure of the diaphragm is less than 2 kg/cm 2 or the pressing down time is less than 10 seconds, the adhesion between the carpet and the unvulcanized rubber sheet will be insufficient, and conversely, the pressing down pressure will be less than 15 kg/cm2. /cm 2 or if the pressing down time exceeds 60 seconds, the pile is likely to be set in a collapsed state due to the influence of residual heat from the mold, and both are unfavorable.

用され、接合圧力の損失が生じない。 During vulcanization, the diaphragm is separated from the carpet and the carpet is pressed directly onto the unvulcanized rubber sheet using pressurized air, so the pile does not fall over and the back side of the carpet is in close contact with the top of the rubber sheet. Therefore, the pressurized air does not pass through the fiber voids of the carpet, so that all the pressure of the pressurized air is used for crimping the carpet, and no loss of bonding pressure occurs.

きる。(Effects of the Invention) This invention pressurizes the carpet through a diaphragm without heating the mold when adhering the carpet to the rubber sheet, and pressurizes the carpet directly with pressurized air during vulcanization. Because it pressurizes,
A mat in which the pile does not collapse and the carpet and rubber sheet are firmly bonded can be obtained, and there is no need to raise the pile after vulcanization. Then, the unvulcanized rubber sheet and the carpet are stacked and placed on a belt conveyor that passes over the lower heating platen, and the belt conveyor is driven to transfer them onto the heating platen, forming an airtight space on the heating platen. However, since the carpet and the unvulcanized rubber sheet are brought into close contact and vulcanized, it is easy to attach and remove the unvulcanized rubber sheet and the carpet, and it is possible to vulcanize multiple sets of the unvulcanized rubber sheet and carpet at the same time. It can be bonded with sulfur to form a mat, and the mat can be mass-produced economically.

とを特徴とするマツトの製造法。1 Place unvulcanized rubber sheets and carpet of a predetermined size on a belt conveyor, transfer the unvulcanized rubber sheets and carpet to the lower heating platen of a press having upper and lower heating platens, and then The press is closed, and a mold having a cavity with an opening at the bottom and a diaphragm that divides the cavity into two is placed on the belt conveyor above the lower heating plate in close contact with the mold. A sealed space is formed surrounding the unvulcanized rubber sheet and the carpet, the diaphragm is then pushed down, the diaphragm brings the carpet into close contact with the unvulcanized rubber sheet, and the diaphragm is then raised to fill the space below the diaphragm. By introducing pressurized air and pressing the carpet onto the unvulcanized rubber sheet and vulcanizing the unvulcanized rubber sheet, the rubber sheet is adhered to the carpet, and then the rubber sheet is bonded to the carpet under the diaphragm. A method for manufacturing matuto, which comprises returning the space to normal pressure and opening the press.
