Abstract
Abstract This invention relates to a duct forming machine strip material feeder alignment compensating system which permits the adjustment of strip material being fed to a mandrel for forming duct. The strip feeder material is fed from a reel mounted on an adjustable platform. The platform is supported by the machine frame for vertical adjustment by a crank operated lead screw. Horizontal and vertical angular compensating adjustments of the strip material feed system are provided by adjustments of a spool axle mounting plate. The axle mounting plate is horizontally and angularly adjustable to keep strip material being fed from a spool to the mandrel of the duct forming machine in proper alignment.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
157 words
In a duct forming machine having reinforcing wire and strip material fed to a rotating mandrel with the strip material overlapping and encapsulating the reinforcing wire the improvement comprising: a spool of flexible strip material rotatably mounted on an axle being fed to said duct forming machine mandrel; platform mounting means for mounting said axle; vertical adjustment means for adjusting the vertical position of said platform mounting means to align said strip material with respect to said rotating mandrel; horizontal adjusting means for adjusting the horizontal position of said axle on said platform mounting means to align said spool with respect to said rotating mandrel; and horizontal angular adjustment means for adjusting the horizontal angular position of said axle with respect to said mandrel; whereby alignment of said spool with said mandrel may be easily made by adjusting said platform mounting means vertically and adjusting the horizontal and angular position of said axle mounted on said platform.
Claim 2
Dependent Claim
157 words
In a duct forming machine having reinforcing wire and strip material fed to a rotating mandrel with the strip material overlapping and encapsulating the reinforcing wire the improvement comprising: a spool of flexible strip material rotatably mounted on an axle being fed to said duct forming machine mandrel; platform mounting means for mounting said axle; vertical adjustment means for adjusting the vertical position of said platform mounting means to align said strip material with respect to said rotating mandrel; horizontal adjusting means for adjusting the horizontal position of said axle on said platform mounting means to align said spool with respect to said rotating mandrel; and horizontal angular adjustment means for adjusting the horizontal angular position of said axle with respect to said mandrel; whereby alignment of said spool with said mandrel may be easily made by adjusting said platform mounting means vertically and adjusting the horizontal and angular position of said axle mounted on said platform.
Claim 3
Dependent Claim
44 words
The duct forming machine according to claim 1 in which said platform mounting means has a flange having a dovetail joint engaging a mating dovetail joint on a frame portion of said duct forming machine whereby said platform mounting means may be vertically adjusted.
Claim 4
Dependent Claim
57 words
The duct forming machine according to claim 2 including a lead screw passing through a threaded bushing on said platform mounting means; one end of said lead screw resting on a socket mounted on said duct forming machine whereby rotation of said lead screw causes vertical movement of said platform mounting means relative to said rotating mandrel.
Claim 5
Dependent Claim
28 words
The duct forming machine according to claim 1 in which said horizontal adjusting means comprises; a bearing plate supporting said axle; means for horizontally adjusting said bearing plate.
Claim 6
Dependent Claim
24 words
The duct forming machine according to claim 4 in which said bearing plate is mounted on said platform mounting means for simultaneous adjustment therewith.
Claim 7
Dependent Claim
50 words
The duct forming machine according to claim 5 in which said horizontal adjusting means includes; a rack gear on said bearing plate; a rotatable shaft; gear means on said rotatable shaft engaging said rack gear; whereby rotation of said shaft rotates said gear means to horizontally adjust said bearing plate.
Claim 8
Dependent Claim
33 words
The duct forming machine according to claim 6 in which said horizontal angular adjustment comprises means for angularly deflecting said bearing plate whereby the horizontal angle of said spool axle can be adjusted.
Claim 9
Dependent Claim
44 words
The duct forming machine according to claim 7 in which said means for angularly deflecting said bearing plate comprises a flange on said bearing plate; and a fixed thumbscrew abutting said flange whereby rotation of said thumbscrew causes angular deflection of said bearing plate.
Claim 10
Dependent Claim
28 words
The duct forming machine according to claim 3 in which said horizontal adjusting means comprises; a bearing plate supporting said axle; means for horizontally adjusting said bearing plate.
Claim 11
Dependent Claim
28 words
The duct forming machine according to claim 9 in which said horizontal adjusting means comprises; a bearing plate supporting said axle; means for horizontally adjusting said bearing plate.
Claim 12
Dependent Claim
24 words
The duct forming machine according to claim 10 in which said bearing plate is mounted on said vertical adjusting means for simultaneous adjustment therewith.
Claim 13
Dependent Claim
50 words
The duct forming machine according to claim 11 in which said horizontal adjusting means includes; a rack gear on said bearing plate; a rotatable shaft; gear means on said rotatable shaft engaging said rack gears; whereby rotation of said shaft rotates said gear means to horizontally adjust said bearing plate.
Claim 14
Dependent Claim
33 words
The duct forming machine according to claim 12 in which said horizontal angular adjustments comprises means for angularly deflecting said bearing plate whereby the horizontal angle of said spool axle an be adjusted.
