Abstract
An expandable belt and tread drum with magnetic deck fixing includes an assembly defining a portion of an arcuate outer circumferential working surface of a tire building drum. The assembly comprises a deck segment carrier and one or more magnetic members provided to the deck segment carrier and configured to attach a deck segment to the deck segment carrier by magnetic force.
Claims18
An assembly defining a portion of an arcuate outer circumferential working surface of a tire building drum, the assembly comprising:
- a deck segment carrier;
- a magnet housing rotatably mounted along the deck segment carrier;
- one or more magnetic members provided along the magnet housing and configured to attach a deck segment to the magnet housing by magnetic force;
- wherein the magnet housing is rotatable along a central axis thereof in relation to the deck segment carrier such that the one or more magnetic members may be rotated between a first position in a direction toward a deck segment positioned on the deck segment carrier to attach the deck segment to the magnet housing by magnetic force, and a second position in a direction away from the deck segment positioned on the deck segment carrier to detach the deck segment from the magnet housing.
A deck fixing assembly for an expandable belt and tread drum used to manufacture vehicle tires, comprising:
- an upper ramp portion having a top;
- a magnet housing rotatably disposed on the top of the upper ramp portion, where the magnet housing forms at least one pocket along an outside edge;
- at least one magnet positioned in the at least one pocket of the magnet housing;
- a deck segment set above the upper ramp portion;
- an insert affixed to an underside of the deck segment, where the insert faces the magnet housing and aligns with the at least one magnet;
- a first latch housing connected at an end of the upper ramp portion and deck segment;
- and
- a second latch housing connected at another end of the upper ramp portion and deck segment;
- wherein the magnet housing is rotatable in relation to the upper ramp portion such that the magnet may be rotated between a first position in a direction toward a deck segment positioned on the deck segment carrier to attach the deck segment to the magnet housing by magnetic force, and a second position in a direction away from the deck segment positioned on the deck segment carrier to detach the deck segment from the magnet housing.
