Rolling head for bottle capping machine to roll cover foil on bottle cap, has lever pivotable around pivoting axis, where torque on both sides of pivoting axis corresponds with tolerance of less than specific percentages

摘要

The head (10) has a rotatable rolling arrangement (12) comprising rolling-up rollers (14-17), which are radially moved by a lever. The lever is pivotable around a pivoting axis, which is aligned tangentially to a rotating direction of the rolling arrangement. Torque on both sides of the pivoting axis corresponds to a tolerance of less than 5 percentages. Counter weights are arranged on ends of the lever, where the ends are turned towards the rollers. A control device is fixed in an outer operating position by the lever, and comprises a bevel.
