Wrapping-over device for a tire assembly drum

A wrapping over device for a rotatable solid body tire assembly drum having an axial centerline for wrapping over the tire body edges projecting beyond a bead when the assembly drum is expanded and pressed in position, said wrapping over device comprising:

• an arcuate support;
• at least three conical finger means mounted on said support and defining a curve, and each of said conical finger means being positioned in the direction of rotation of the tire assembly drum, closer to the tire assembly drum axial center line for applying an increased pressure on said tire body projecting edge in the direction of rotation, an extension of said finger means meeting at a common point wherein each successive said finger means exert an increasing force on the body edges;
• a plate shaped pressing roller rotatably mounted on said support at a position between said conical finger means;
• a pivot drive means pivotally mounting said support for rotation about an axis disposed at right angles to the assembly drum axial centerline, said pivot drive means including a first work cylinder for pivoting said support about said axis at right angles at the assembly drum;
• and
• parallel drive means mounting said pivot drive means for movement in a direction parallel to the tire assembly drum axial centerline.
