The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described:
Fig. 3 is the schematic diagram of inlet guide and guards of the anti-band steel frictionally damage of the utility model preferred embodiment, and Fig. 4 is that the B-B of the inlet guide and guards of anti-band steel frictionally damage among Fig. 1 is to cutaway view.As shown in the figure, the inlet guide and guards of anti-band steel frictionally damage comprises base plate 200 and two side plates 300, two side plate 300 symmetries are fixed on the both sides of base plate 200, each side plate 300 is made of the inlet liner plate 301 of pilot tape steel direction of advance and the abrasion-proof backing block 302 of control strip width respectively, and there is corner the junction of inlet liner plate 301 and abrasion-proof backing block 302.
