Flexible drive member for pulling and pushing and fluid-operated moving apparatus

A fluid-operated device moving apparatus comprising:

• a flexible drive member including a toothed belt section including teeth formed on one surface thereof, and ridge members arranged along the length of said toothed belt section on a rear surface of said belt section opposite to the surface on which said teeth are disposed, said ridge members abutting against adjacent ones of said ridge members when said toothed belt section extends straight, and including holding means for holding an at least a fluid hose along said rear surface of said toothed belt section, said flexible drive member having a T-shaped transverse cross-section corresponding to a predetermined T-shaped groove for being guided in said T-shaped groove;
• a fluid-operated device having an engagement section engaging with said T-shaped groove, one end of said flexible drive member being coupled to said fluid operated device for moving said fluid-operated device along said T-shaped groove;
• and
• a drive unit having a toothed pulley having teeth engaging with the teeth of said toothed belt of said flexible drive member for selectively pushing and pulling said flexible drive member along the length direction thereof to thereby selectively push and pull said fluid-operated device along said T-shaped groove.

• a die clamping device having an engagement section engaging with said T-shaped groove, one end of said flexible drive member being coupled to said die clamping device for moving said die clamping device along said T-shaped groove between a die clamping position and a standby position;
• and
• a drive unit having a toothed pulley having teeth engaging with the teeth of said toothed belt of said flexible drive member for selectively pushing and pulling said flexible drive member along the length direction thereof to thereby selectively push and pull said die clamping device along said T-shaped groove.
