である。(Prior Art) The tile carpet referred to in the present invention is, for example, a square, rectangle, diamond, or even rougher shape of about 50 cm x 50 cm, and the area of one piece is, for example, 0.
It is a plate-like carpet that can be easily installed by arranging and fixing it on the floor with a length of about 0.5 to 2 m'' without any gaps.

った。In addition, during the processing process, the materials that make up the curved base material and backing layer stabilize the expansion and contraction behavior caused by the heat and mechanical forces that are applied to each individual material during processing. In order to alleviate distortion, it was common to include a process called aging, in which the material was left for a long period of time.

ある。(Problem to be solved by the invention) For this aging, after lining processing, shrinkage,
It is necessary to roughly cut the material to a size with a cutting allowance, and then leave it alone for at least one day without applying any external force.Precise cutting of the predetermined shape and size is performed after this aging process. I had to. If precision cutting is performed without this knee song, changes will occur over time after cutting, and the dimensions of the product will fluctuate. Therefore, the above-mentioned aging is indispensable, and it has been impossible to carry out backing processing and precision cutting as a continuous process (Means for solving the problem). A tile characterized by applying a vinyl chloride paste sol, performing a heat treatment, cooling the carpet by spraying cold water directly onto the back surface of the carpet, and then continuously cutting it into a predetermined shape and size. This is a method for manufacturing carpets.
（実施例） 以下、本発明の実施例を図によって説明する。(Example) Embodiments of the present invention will be described below with reference to the drawings.

こり、製品にまで悪影響を及ぼすため、上記現象を防止
するのにも有効である。The carpet base material l includes Wilton carpet, tufted carpet, needle punch carpet, etc., and is supplied in roll form. Both ends of the carpet base material are cut by a cutter 2. This cutter is preferably a circle cutter, which is not only effective in setting the processing width of the carpet base material, but also particularly in the case of tufted carpets, it can be used to distinguish between areas of the base fabric where pile threads are flocked and areas where pile threads are not flocked. Then, the degree of shrinkage when heated in the preheating furnace of 3 is different,
This method is also effective in preventing the above-mentioned phenomenon, since the phenomenon of waving (flare) occurs on both ends of the carpet base material and has an adverse effect on the product.

である。予熱は、少なくとも１６０℃以上、好ましくは
１８０”Ｃ以上にカーペット基材の裏面が昇温するまで
加熱する。Next, the carpet base material l enters a preheating furnace 3, which pre-relaxes the expansion and contraction behavior of the carpet base material due to heat when heat-treating the polyvinyl chloride paste in the heating furnace 1o. This is a preheating furnace to suppress the occurrence of distortion. Preheating is performed until the back side of the carpet base material is heated to at least 160°C or higher, preferably 180''C or higher.
パイル糸によっては、（例えばＰＰ等は）このような高
温では溶融するために特にカーペット基材の裏面からの
加熱が不可欠であり、好ましくは輻射による加熱方式が
望ましい。Some pile yarns (such as PP) melt at such high temperatures, so heating from the back side of the carpet base material is essential, and heating by radiation is preferably used.

ト基材が加熱される時に、張力のかからないフリーな状
態で裏面からチェーンベルトを通して処理される。In the preheating process, the carpet base material l is placed on the endless chain belt 4 and transferred, but when the carpet base material is heated in the preheating furnace, it is processed through the chain belt from the back side in a free state without any tension.
その後、搬送ベルト５てカーペット基材を張力のかから
ない状態のままポリ塩化ビニルペーストゾルと貼り合せ
が出来るようベルトにカーペット基材を乗せた状態で搬
送を行う。Thereafter, the carpet base material is conveyed by the conveyor belt 5 with the carpet base material placed on the belt so that the carpet base material can be bonded to the polyvinyl chloride paste sol without applying any tension.
一方、ポリ塩化ビニルペーストゾル７は、テフロンコー

。On the other hand, the polyvinyl chloride paste sol 7 is dropped onto a Teflon coated endless belt 8, and the coating thickness of the polyvinyl chloride paste sol is controlled by a doctor knife 6.
裏打ち材の中間層にガラス基布なとを挿入する場合には
、複数のドクターナイフを設置しその間で挿入を行うこ
とができる。When inserting a glass base cloth into the intermediate layer of the backing material, a plurality of doctor knives can be installed and insertion can be performed between them.
テフロンコーティングエントレスヘルト８は、ポリ塩化
ビニルペーストゾルに対し離型性を有するものが望まし

あることが望ましい。After the heat treatment, in order to release the polyvinyl chloride paste sol from the Teflon belt, the back surface of the backing material is cooled to at least 80° C. or lower using the cooling plate 11, but cooling is performed indirectly through the belt. It is desirable that the cooling water flowing through the cooling plate be as low as possible, preferably 10° C. or lower.
つづいて、冷却ゾーン１２で好ましくは１０”Ｃ以下に

ペットを４０℃以下、好ましくは３０℃以下になるまで
冷却を行う。Subsequently, the carpet is cooled to below 40°C, preferably below 30°C, by spraying cold water, preferably below 10"C, directly onto the backing in the cooling zone 12.
その後、連続して精富裁断機１３て所定の形状、寸法に

（効果）
本発明により、裁断後の経時収縮率は、冷却ゾーン１２
を通さないですぐに裁断した場合は、０．１％であった
ものが０．０２％となった。(Effect) According to the present invention, the shrinkage rate over time after cutting is reduced by the cooling zone 12.
When the material was cut immediately without passing through it, the percentage was 0.1%, but it became 0.02%.

短縮等の効果は、非常に大きい。Therefore, since the aging process is not necessary, the shrinkage margin during conventional rough cutting and the loss during cutting are reduced, the environmental conditions during aging can be controlled, product inventory is reduced, and delivery time is reduced.
The effects of shortening etc. are very large.
