Heat sealing techniques for bonding sheet materials

摘要

Various embodiments of a bonding machine structured and programmed for bonding or laminating one or more materials is disclosed. In one embodiment, the bonding machine comprises a support bar and one or more bonding arms movably coupled to the support bar. Each of the bonding arms may include a heating bar including one or more heating elements, and an actuator configured to provide movement of the bonding arm between the support bar and a material to be processed. At least one of the bonding arms may be programmed to operate with a temperature setting, pressure setting, application timing setting, timing sequence setting, or center position setting which is independent of at least one of the other bonding arms.

1. A bonding machine for bonding two fabric layers together, the bonding machine comprising:
a bonding table for supporting the two fabric layers thereon, the two fabric layers having a thermally-activated bonding agent therebetween; a support bar connected to the bonding table; a plurality of independently controllable bonding arms movably coupled to the support bar, each of the bonding arms comprising:
a heating bar including at least one heating element; andan actuator configured to provide movement of the heating bar between the support bar and the bonding table supporting the two fabric layers thereon, wherein pressure and heat from the heating bar cause the bonding agent to bond the two fabric layers; and a controller connected to the plurality of independently controllable bonding arms to independently control:
actuation of the bonding arms such that each bonding arm's motion is independent of the other bonding arms;pressure applied by the bonding arms when actuated; andthe temperature of the at least one heating element of the heating bar of each of the plurality of bonding arms, such that when the bonding arm is actuated, the thermally-activated bonding agent between the two fabric layers is sufficiently heated to bond the two fabric layers.
