[0002] Artificial leather is a kind of plastic products, which appearance and feel are similar to leather and can replace it. It is usually made by coating synthetic resin and various plastic additives on fabric. There are three types of artificial leather: PVC artificial leather, PU artificial leather and PU synthetic leather. Fabric is usually used as the base, and a layer of resin mixture is coated or attached on it. Then, it is heated to plasticize and rolled or embossed to flatten. Artificial leather needs to be cut and wound during production. The base fabric is difficult to stretch completely during unwinding, which can cause uneven tension and wrinkles. Therefore, a stretching device is needed to stretch the artificial leather flat for subsequent processing.
