Abstract
Bead releasing and removing head for a tire fitting machine comprising a support frame (2) anchored to the tire fitting machine and supporting at its top at least a bead releasing disk (3) and a bead removing tool (4), having a working tip (7), wherein the removing tool (4) is slidably supported by said head and comprises driving means (5) suitable for displacing it, upon control, so that the working tip (7) is movable between an advanced working position and a withdrawn rest position.
Claims20
A bead releasing and removing head for a tire assembling/disassembling machine, including an upright structure anchored to said tire assembling/disassembling machine, a bead releasing disk and a bead removing tool having a work tip, both supported at a top of said upright structure, wherein the said bead removing tool is slidably supported by said head on the same side and in the same direction as said bead releasing disk and comprises driving means arranged to cause said bead removing tool to be displaced, upon control, between an outwardly extended working position and a withdrawn rest position, while sliding over and flush with said bead releasing disk along a curved path, thereby overtaking said bead releasing disk to reach said extended working position.
A bead releasing and removing head for a tire assembling/disassembling machine, including an upright structure anchored to said tire assembling/disassembling machine, a bead releasing disk and a bead removing tool having a work tip, both supported at a top of said upright structure, wherein said bead removing tool is slidably supported by said head and comprises driving means arranged to cause said bead removing tool to be displaced, upon control, whereby the worktip is moveable between an outwardly extended working position and a withdrawn rest position,
- wherein said removing tool is provided with sliding supporting and guiding means and said supporting and guiding means comprise at least two pairs of rollers idly mounted on said support structure.
A bead releasing and removing head for a tire assembling/disassembling machine, including an upright structure anchored to said tire assembling/disassembling machine, a bead releasing disk and a bead removing tool having a work tip, both supported at a top of said upright structure, wherein said bead removing tool is slidably supported by said head and comprises driving means arranged to cause said bead removing tool to be displaced, upon control, whereby the worktip is moveable between an outwardly extended working position and a withdrawn rest position,
- wherein said driving means of said bead removing tool comprises a rack formed in a section of said removing tool, a pinion in meshing engagement with said rack and a motor for said pinion.
