Abstract
A machine for applying hot-melt products having a structural body (1) provided longitudinally on the inside with a recess (2) extending between a supply inlet (3) for the product in solid state and a discharge outlet (4) through which the product exits in fluid state for its application, the recess (2) having a spindle (5) fitted with a helical blade (9) for conveying the product through a feeding zone, a melting zone and/or a compression zone, wherein the recess (2) has a conical zone (2.1) with a narrowing separating the feeding zone from the melting zone for compacting the hot-melt product, and on the inner periphery of the conical zone (2.1) having a plurality of indentations (8).
Claims14
A machine for applying hot-melt products, comprising:
- a structural body (1) provided longitudinally on the inside with a recess (2) extending between a supply inlet (3) for the product in solid state and a discharge outlet (4) through which the product exits in a fluid state for its application,
- a spindle (5) disposed in the recess and fitted with a helical blade (9) for conveying the product through a feeding zone, a melting zone and/or a compression zone,
- wherein the recess (2) comprises a conical zone (2.1) with a narrowing separating the feeding zone from the melting zone, an inner periphery of the conical zone (2.1) includes a plurality of indentations (8), and the supply inlet (3) opens into the recess (2) in a laterally offset direction with respect to the longitudinal axis of the spindle (5) and directs entry of the product tangentially away from the longitudinal axis of the spindle (5).
