ABSTRACT:
Method and apparatus are disclosed for preventing rotation of bottles in a capping machine while caps are screwed onto bottle necks with capper heads which develop slight axial forces. An especially configured stationary guide member develops an off-center, mechanical force on the shoulder of the bottle which produces an anti-rotation frictional force at the bottle base while wedging the bottle into frictional engagement with an especially configured neck pocket in the capper star wheel. The guide and neck pocket are shaped to maintain the bottle in axial alignment with the capper head while the cap is started onto the bottle neck which support is removed when the cap is tightened so that the aforedescribed pocket frictional engagement can occur.
