In the known three-cam self-centered latropes of persdv11 / 1, move the cam to the center of the cartridge or away from it, either by hand or by actuating or electrically. For clamping the product 1 of such ions, it requires a considerable amount of effort from the side of the worker; When using a PIE drive, a compressor installation is required; the electric drive due to the mass of difficult-to-balance parts breaks up and quickly breaks down; shpitdel CTani a.

The self-propelled three-cam arm of PGM has;) are quietly flawed, due to the use of a folding worm mechanism for moving the cam 01, which engages with the gearwheel nut and any chuck and is hand-drawn or electrically through the flexible shaft.
