The present invention relates to the manufacture of a packaging band, specifically, a polypropylene band (PP BAND), which is a material that can replace the existing polyester band or steel band (PP BAND) by stretching the band by heating with heated hot air in the transport state It is to improve the strength of the product and to manufacture it with stable quality. It can prevent the excessive consumption of electricity, the relatively high defect rate, the decrease of the tensile force and the elongation force, which are problems in wet use, as well as simplify the work and simplify the process. The present invention relates to a dry drawing apparatus for forming a band for packaging, which can reduce production costs and improve economic efficiency.

Generally, a strap band is used to wrap a medium and large household appliance in a packaging box or to prevent a product from being separated while the industrial and building materials are loaded. The band used for packaging work in such a packing box or the product itself should be provided with corrosion resistance, heat resistance, safety and environmental friendliness as well as elasticity and tensile strength.

However, in the conventional band, the manufacturing process is mostly wet, that is, when the band is stretched primarily by heating water and stretching the band by the heated water. When the product is packaged and transported after the back has been sharply fallen off, when exposed to shock, moisture, and ultraviolet rays from the outside, the contraction and expansion occur repeatedly, and the tightly banded band becomes loose or broken, causing the loaded product to scatter. This was followed by the closure of the product which caused great damage to the product and the safety of the product.

In addition, in the case of wet, as the band is drawn secondarily, electricity consumption is excessively about four times higher than dry heating the band directly to the heater. There is a problem.

In addition, in the case of the wet type, the rollers are provided in each of the heaters for stretching the band and the transfer paths of the band inside the stretching machine, and the complexity of the configuration is caused, and the thickness of the band itself according to the defective rate of the roller is not constant. Since the defect rate also exists, there are problems that eventually lead to the complexity of the work and the inefficiency of the process.

Excessive consumption of electricity due to water heating for stretching keys, which is a problem in wet use, and relatively high defect rate, tensile strength and elongation force due to stretching the band due to heated water. In addition to preventing the deterioration of the roller as much as possible, it is possible to simplify the work and reduce the complexity by eliminating the defect rate due to the roller damage and the delay and complexity due to the failure of the roller itself. The object of the present invention is to reduce production costs and improve economics due to simplicity. have.
