Abstract
The invention relates to a device for dispensing a fused material. This device comprises a heating chamber, into which a rod of the material to be dispensed is progressively introduced. A clamping member is arranged so as to catch the rod. When a push is exerted on an end of the rod, the clamping member is carried away with the rod towards the heating chamber while biasing a resilient return element. When a push is no longer exerted on the rod, the last is brought rearwards under the action of the biased return element on the clamping member. This avoids untimely dispensing fused material.
Claims11
A device for dispensing a fused material such as a thermoplastic adhesive, comprising a housing equipped with a heating chamber including a delivery nozzle and an inlet tube for progressively introducing a rod of the material to be dispensed into said heating chamber, whereby the material of the introduced rod is progressively fused and expelled outside of the heating chamber through said delivery nozzle, a clamping member arranged so as to catch the rod, so that said clamping member is carried away with said rod when a push is exerted on said rod, and means for generating a resilient return force when said clamping member is carried away with said rod, so that said rod is brought rearwards under the action of said return force when a push is no longer exerted on said rod.
