PROCESS FOR MAKING ABRADING ROLLERS, SPIRAL WOUND, FOR ABRADING MACHINES PROVIDED WITH ONE OR MORE ROLLERS, PARTICULARLY FOR SHEET MATERIALS, SUCH AS CLOTHES AND THE LIKE, AND ROLLERS OBTAINED WITH SUCH PROCESS AND SOFT AND SPEEDY ABRADING MACHINES USING SUCH ROLLERS

摘要

at each end of the roller (3) has a blocking device (6).the main bodies of the locking devices and tensioning a bladder (9), which, once the pressure has a dual effect of freezing and swelling shown by the arrows (55, 55 '), and, indirectly, a third fixing suction effect is shown by the flu00e8c he (55).obtained in conjunction with a spiral coupling that can be moved between the blocking element (90) including an annular end members of the spool (3), and a hub (91) set by a setting coil (39). the rollers (3) are made, at least in the envelope (30), a material with a specific gravity less than that of the light alloy.
