Clamping pin for roller unwinding device of rotary printing machine, has protrusions formed with spatial dimension and different elevations in clamping jaw whose support surface is extended along pin element circumferential direction

摘要

The clamping pin (03) has a support pin element that is provided along rotational axis (08) of the clamping pin main portion. A movable support pin element clamping jaw is arranged along radial direction of the pin main portion. A support surface of the clamping jaw is used as a reference surface and is extended along circumferential direction of the support pin element with respect to rotation axis of the pin main portion. Two protrusions are formed with the specific spatial dimension and different elevations in the clamping jaw.
