　　1) The SJ-45 extruder is commonly used, with a screw diameter of 45mm and a length to diameter ratio of L/D=20:1. The screw is a mutation type screw, and the head is either a straight or a right angle head.

　　(2) The cooling water tank is 0.7mX0.4mX0.8m, and the height of the water tank should be freely adjustable.

　　(3) The traction machine currently uses a unidirectional stretching device, and the traction adopts a double roller internal rotating gantry press down type traction roller. The main types are:; Use two continuously variable speed devices to adjust the roller speed separately, forming different linear speed differences between the front and rear stretching rollers.

　　(4) There are two types of stretching groove stretching: dry stretching and wet stretching. From the perspective of heating methods, there are steam water bath, electric water bath, far infrared heating, hot air circulation, drum, oil bath, and other methods. Considering production costs and ease of implementation, steam and electric hot water baths are currently mostly used for heating. The sink is 1.5-2rn long.

　　(5) There are two methods for winding packaging tape. The width of the finished product is equal to the width of the tape, called narrow coil winding. Mainly used for manual packaging of belts. The width of the finished product is greater than the width of the belt, which is called adjustable coil winding, mainly used for mechanical packaging of belts.
