Abstract (en)
[origin: US6464785B1] An application head (11) for contract-free application of hot-melt adhesive onto a width of material (22) has a housing (12) with a control slide chamber (20). A cylinder control slide (13) is supported and is rotatably drivable in the housing. At least one supply aperture introduces an adhesive into the control slide chamber (20). A slotted nozzle (18) releases the adhesive. The slotted nozzle is controllable by the cylinder control slide (13). The nozzle extends transversely to the direction of movement of the width of material (22). The cylinder control slide (13) has a cylindrical surface which is able to seal the slotted nozzle (18) from the inside. The control slide (13) also has surface grooves (17) in the cylindrical surface. The grooves, as a function of their rotational positions, are able to communicate with the slotted nozzle. Furthermore, the cylinder control slide (13) inside the control slide chamber, has either an inner cavity (29) supplied with medium through a supply aperture, as well as radial exit bores (28) leading from the inner cavity into the surface grooves, or it has a helical or spiral-shaped surface groove in the cylindrical surface, as well as a storage volume for medium, which communicates with the at least one surface groove.
