METHODS AND APPARATUS FOR FORMING TREAD STRIPS IN CLOSED-LOOP SYSTEM
Particular embodiments of the invention include a closed-loop tread strip forming unit (100) and methods for forming tread strips using a closed-loop unit. Embodiments of such forming units include a tread strip extruder (110) located at a pre-cure end of the closed-loop tread strip forming unit. Such units include an uncured tread strip handling assembly (120) configured to transport the first uncured tread strip from the first tread strip extruder and to a first tread strip mold member (130). The unit further includes a curing press (150) having an inlet and an outlet, a pre-cure mold handling assembly (140) configured to insert the loaded tread strip mold member into the curing press, a post-cure mold handling assembly (160) configured to receive the loaded tread strip mold member from the outlet of the curing press, a return assembly (170) configured to transfer the first tread strip mold member to the pre-cure end to complete a closed-loop.
DEVICE AND METHOD FOR HANDLING TYRES AND TYRE CURING PRESS
A device and a method for handling tires, as well as a tire curing press including a device of this type. The device for handling tires includes a fork which can be moved under a vulcanized tire in a tire curing press, such that the tire can be taken up by the fork and unloaded from the vulcanization chamber of the tire curing press.
Method and plant for handling a green tyre for bicycle
A green tyre (2) for bicycles is built, comprising at least one carcass ply (4) having axially opposite end flaps (4a) engaged with respective bead cores (5) and a tread band (6) applied in a radially outer position around the at least one carcass ply (4). The built tyre (2) removed from the building drum, is profiled so as to translate the tread band (6) in a radially outer direction with respect to the bead cores (5), so as to impart a cross-sectional convex profile to the tyre (2) in a radially outer direction. The profiled tyre is engaged by means of a transfer member (31) comprising a gripping device (30) which retains it at the radially outer surface (2b) so as to maintain the cross-sectional convex profile in a radially outer direction.
METHOD AND DEVICE FOR VULCANIZING TIRES
A method and a device for vulcanizing tires. The device and method allow a small width and an inexpensive construction of the device in particular by virtue of the special design of or the material flow produced by the device and method. The device has at least one vulcanization chamber and at least one unloader for unloading an at least partially vulcanized tire out of the vulcanization chamber. The device additionally has at least one depositing device, at least one sliding device, and a transport belt for transporting the tire away.
METHOD AND PLANT FOR PRODUCING TYRES FOR VEHICLE WHEELS
Method and plant for producing tyres for vehicle wheels in which: each vulcanizer (30) of a plurality of vulcanizers (30) is associated with a respective pick-up logic of green tyres from at least one storage area (20) of green tyres; upon each request to vulcanize a green tyre in a vulcanizer (30) of the plurality of vulcanizers (30), the pick-up logic associated with said vulcanizer (30) is applied to select and pick up a green tyre from the storage area (20); the respective pick-up logic associated with each vulcanizer (30) comprises a first pick-up rule of green tyres from the storage area (20) and, for at least one of the plurality of vulcanizers (30), the first pick-up rule is changed into at least one second pick-up rule at least once during the production in the plant (1) of at least one lot of tyres.
Dipping bath compositions for treating reinforcing inserts
The present invention relates to an aqueous, solids-containing dipping bath composition for treating reinforcing inserts for rubber products comprising the following components or consisting of these components, (A) at least one blocked MDI mixture, the MDI mixture comprising MDI oligomers of formula (I), n being a whole number from 1 to 8, and MDI monomers; (B) at least one latex; (C) at least one compound selected from the group consisting of polyacrylates, lignin derivatives and mixtures hereof; and (D) possibly at least one additive; the dipping bath composition being essentially free of epoxides, and the dipping bath composition being essentially free of resorcinol, formaldehyde and the reaction products thereof. ##STR00001##
TIRE MOUNTING MACHINE
A tire holding device of a tire mounting machine grasps the bead section of a green tire by chucking paddles and places the green tire around an upright cylindrical vulcanization bladder. A bladder device of the tire mounting machine expands the vulcanization bladder to press same against the inner surface of the green tire, and sets the green tire in a vulcanization-mold. On a lower portion of each chucking paddle, guide extensions are formed to extend in the two circumferential directions. Between adjacent chucking paddles, the guide extensions extend toward each other and constantly overlap each other to prevent the expanding vulcanization bladder from contacting the radially inner surface of the bead section and from stripping the non-vulcanized rubber of the green tire.
TIRE VULCANIZATION SYSTEM, AND VULCANIZED TIRE MANUFACTURING METHOD
A tire vulcanization system is configured to deliver a vulcanized tire carried out from a vulcanizer by a tire conveyance device to a PCI device at a first position, and attaches an upper lid. The PCI device mounted with the upper lid is moved from the first position to a second position by a PCI moving portion. The tire conveyance device is configured to receive the raw tire disposed above the PCI device moved to the second position and carry the raw tire into the vulcanizer.
NUT FOR A CLAMPING MECHANISM OF A VULCANIZING PRESS, CLAMPING MECHANISM, VULCANIZING PRESS AND SUPPORT DEVICE FOR COMPONENTS OF A VULCANIZING PRESS
The invention relates in particular to a nut 1 for a clamping mechanism 10, a clamping mechanism 10 comprising a tie bolt 11 and two nuts 1, a vulcanizing press 20 comprising clamping mechanisms 10 and a support device 23.
METHOD FOR VULCANIZING A TIRE
A method for vulcanizing a tire with a tire vulcanization machine having closing force unit for the treatment space of the tire vulcanization machine. The closing force unit having a base plate and at least one linear drive for the displacement and force application of a mold pressure plate, wherein the at least one linear drive is an integral part of the base plate so that a compact and stringent structure of the closing force unit is supported.
