When pushing and pulling with a strip, for example, foreign matter such as chips may enter the T-groove for pushing and pulling guides formed in the support frame of a processing machine, or resistance to the pushing and pulling may occur due to other reasons. As a result, the drive roller that pinches the transmission band may slip. The friction caused by this slip may cause the transmission band plate to wear out, or the transmission band plate may burn out due to the frictional heat.
本考案はこのような難点を解消した帯板伝動式
