US Patent:

41477464, Apr 3, 1979

Filed:

Feb 21, 1978

Appl. No.:

5/879284

Inventors:

Gerald V. Dever - Trumbull CT
Louis R. Chiocchio - East Haven CT

Assignee:

Olin Corporation - New Haven CT

International Classification:

B29D 2704

US Classification:

264 39

Abstract:

An improvement in the generation of foam from a mixture of foam-forming material in a structure having a preferred configuration. Conveying means are used to convey the structure along a horizontal path. A plurality of foam gun heads are mounted in spaced relationship to each other over and transverse to said horizontal path. Each foam gun head includes a foam dispensing outlet and valve means for controlling the discharges of the foam-forming materials therefrom. First, sensing means are provided upstream of the foam dispensing outlets for sensing the passage of the structure thereby. A plurality of second sensing means are positioned upstream of the foam dispensing outlets in spaced relationship to each other in a direction transverse to the horizontal path, each one of the second sensing means being associated with one foam gun head for sensing the presence of the structure in a vertical direction. The valve means in a foam gun head is opened in response to the first sensing means sensing the structure and its associated second sensing means also sensing the structure. The valve means of a given foam gun head is closed in response to its associated second sensing means detecting the absence of structure.
