Abstract
This invention relates to a mechanism for effecting the synchronized rotation of a rotary anvil employed in a heat sealing operation on thermoplastic sheet material with the linear movement of the thermoplastic sheet moving under the rotating anvil. One specific application of the invention is the heat sealing of the lateral edges of a thermoplastic sheet wrapped around a battery plate. The linear movement of the mechanism carrying the wrapped battery plate is utilized to rotate the rotary heat sealing anvil in exact synchronism with the movement of the wrapped battery plate beneath the anvil.
