Abstract
Method and apparatus for building annular tire components such as steel cord tread reinforcements, in which a measuring drum is employed to receive strip material and simultaneously to feed it to a component building former. The strip material laps a portion only of the measuring drum, and a measured length of the strip is severed on the measuring drum and the major portion of the length of strip is transferred to the building former by rotation of the measuring drum through substantially a whole revolution.
Claims10
A method for the manufacture of an annular tire component from strip material comprising feeding the strip material to a measuring drum of predetermined circumference and rotating said measuring drum simultaneously with the feeding of the strip to transfer the material to a building former, the material being arranged throughout the feeding and transfer of the strip material to lap a portion only of the measuring drum, and severing a measured length of the strip on the measuring drum, the length of strip being transferred to the building former by rotation of the measuring drum through substantially a whole revolution.
Apparatus for the manufacture of an annular tire component from strip material comprising a measuring drum of predetermined circumference arranged to transfer strip material to a component building former, means for supplying strip material to the measuring drum simultaneously with the transfer of material from the drum to the former whereby the material laps a portion only of the measuring drum during the processes of feeding and transfer, and cutting means for severing a length of the strip on the measuring drum, said predetermined circumference of the measuring drum being such that the major portion of the length of the strip is transferred to the building former by rotation of the measuring drum through substantially a whole revolution.
Apparatus for the manufacture of an annular tire component from strip material comprising a component building former, a measuring drum of predetermined circumference arranged to transfer strip material to said component building former and having a movable portion in the form of a triangular arcuate flap pivoted about an axial line adjacent the circumference of the said measuring drum, means for supplying strip material to the measuring drum simultaneously with the transfer of material from the drum to the former whereby the material laps a portion only of the measuring drum during the processes of feeding and transfer, and cutting means for severing the material after the drum has rotated through substantially a whole revolution, means being provided to move said flap to extend its pointed end outwardly from the drum to apply an end of a strip of material to the said former.
