A nozzle for applying adhesive or other liquid to a surface comprises a box-like member with a slot in one of its faces, and an internal partition separating first and second components in the box-like member. One or more projecting portions of one edge of the partition extend into the slot, while other portions of the partition's one edge are recessed to form a weir over which liquid may flow between the components. The slot, through which liquid passes for application to the surface, is thus an interrupted slot, applying a series of short lengths of liquid to the surface, which is of advantage in obtaining a clean separation of the nozzle and the surface after liquid application. The box-like member may be in two parts, one on each face of the partition, and these three members may be bolted together to allow easy replacement of the partition if a change of slot configuration is required.
A nozzle for use in applying adhesive or other liquid to a surface, comprising a box-like member having an orifice in the form of a straight slot formed in one face thereof, and a partition fixedly mounted inside said member to form first and second compartments therein, one edge of said partition being directly opposite said orifice, said one edge having at least one projecting portion extending into and closing a corresponding portion of said slot, and at least two other portions each spaced from the inner end of said slot so as to form a weir over which liquid may flow from said first to said second compartment, said projecting portion of said one edge of said partition being narrower than said other portions of said one edge.
A nozzle for use in applying adhesive or other liquid to a surface, comprising a box-like member having an elongated opening formed in one face thereof, and a partition fixedly mounted inside said member to form first and second compartments therein, said partition having a castellated edge adjacent said opening comprising at least one projecting portion extending into and closing a corresponding portion of said opening to define an orifice at each side thereof, and at least two recessed portions each spaced from the inner end of said opening, so as to form a weir over which liquid may flow from said first to said second compartment.
An improved nozzle for applying liquid such as adhesive to a surface and adapted to minimize critical separation and consequent contamination of adjacent objects, said nozzle comprising:
