Abstract
A device for storing and transferring strip sections of rubber produced intended for making a tire cover, includes a storage cylinder mounted to rotate about a horizontal axis of revolution on a frame which is in turn mounted on a support. A flexible strip forming a closed loop is movable around part of the cylinder. The cylinder and the flexible strip are suitable for clamping a strip section between one another. The frame is mounted to rotate on the support about a second axis oriented perpendicular to the axis of revolution of the storage cylinder.
Claims15
A device for storing and transferring rubber strip sections for making a tire cover, comprising a storage cylinder mounted for rotation about a substantially horizontal axis of revolution on a frame, the frame mounted on a support for rotation about a substantially vertical axis, the support being mounted on a movable carriage said device including a flexible strip forming a closed loop and movable around part of the cylinder, and a set of guides for guiding the flexible strip, with the cylinder and the flexible strip arranged for clamping and frictionally driving a rubber strip section held between the cylinder and the flexible strip to wind the rubber strip section around the cylinder.
A tire-making facility comprising:
- a plurality of supply stations arranged adjacent one another in a row, the supply stations containing respective rubber sections for making a tire,
- a tire-building site,
- a storage-and-transfer device movable along the row of supply stations between the tire building site and the row of supply stations, the device including:
- a movable carriage,
- a frame mounted on the carriage for rotation about a substantially vertical axis, and
- a storage cylinder mounted on the frame for rotation about a substantially horizontal axis for storing a rubber section thereon,
- wherein the carriage is movable to positions enabling the storage-and-transfer device to receive a rubber section from a selected supply station onto the storage cylinder and transfer the rubber section to the tire-building site from the storage cylinder after rotating the frame by about 180 degrees about the substantially vertical axis.
A process for making tires utilizing a device for storing and transferring rubber sections for making a tire, the device including a frame rotatable about a substantially vertical first axis, and a storage cylinder mounted on the frame for rotation about a substantially horizontal second axis, the process comprising the steps of:
- A. winding from a supply station a rubber section of predetermined length around the storage cylinder while rotating the storage cylinder about the second axis,
- B. pivoting the frame by about 180 degrees about the first axis,
- C. moving the frame on a movable carriage relative to the supply station for positioning the device opposite a tire building site, and
- D. subsequent to steps B and C unwinding the rubber section from the storage cylinder and transferring the rubber section to the tire-building site.
A process for making tires utilizing a device for storing and transferring rubber sections for making a tire, the device including a frame rotatable about a substantially vertical first axis, and a storage cylinder mounted on the frame for rotation about a substantially horizontal second axis, the process comprising the steps of:
- A. winding from a supply station a rubber section of predetermined length around the storage cylinder while rotating the storage cylinder about the second axis which intersects the storage cylinder and the first axis,
- B. pivoting the frame by about 180 degrees about the first axis which intersects the second axis at the mid-line of the storage cylinder,
- C. positioning the device opposite a tire building site, and
- D. subsequent to steps B and C unwinding the rubber section from the storage cylinder and transferring the rubber section to the tire-building site.
