    Abstract: An applicator system for melting thermoplastic material and supplying the molten or liquid material under pressure and at a controlled temperature to an applicator head or gun. The material is heated in a reservoir from which it is pumped to the applicator gun by a single-acting, sleeve-type piston pump. The pump is driven by a single-acting reciprocating air motor. There is an interlock valve associated with the air motor for controlling opening and closing of a valve of the gun. This interlock valve insures that the gun valve is never opened and molten material is never dispersed from the gun except when the molten material pressure is at a predetermined operating level.

    Abstract translation: 一种用于熔化热塑性材料并在压力和受控温度下将熔融或液态材料供应到涂抹头或枪的涂抹器系统。 材料在储存器中被加热,通过单作用的套筒式活塞泵将其从泵送到施加器枪。 泵由单作用往复式气动马达驱动。 存在与气动马达相关联的联锁阀,用于控制枪的阀的打开和关闭。 该互锁阀确保枪阀从不打开,并且熔融材料不会从喷枪分散,除非熔融材料压力处于预定的操作水平。
