Abstract

Claims (45)

1. A mechanism for use in adjusting the position of components in a machine, comprising:

A. an elongate shaft assembly, comprising:

i. at least one primary shaft segment; and

ii. at least one secondary shaft segment removably coupled to said primary shaft segment, said secondary shaft segment including a first gear element disposed thereon;

B. at least one projection shaft extending in a direction transverse to said elongate shaft assembly and including a second gear element disposed on a proximal end portion thereof, said second gear element being coupled to said first gear element whereby rotation of said elongate shaft assembly translates into rotation of said projection shaft, said projection shaft capable of being coupled to the components such that rotation of the projection shaft operates to adjust the position of the components; and

C. a support frame accommodating said secondary shaft segment and said proximal end portion, wherein said support frame includes at least one bearing for supporting said secondary shaft segment.

2. A mechanism according to claim 1 wherein said primary and secondary shaft segments are joined by a half-lap joint.

3. A mechanism according to claim 1 wherein said projection shaft is coupled to said components.

4. A mechanism according to claim 1 wherein rotation of the projection shaft operates to reposition the components perpendicularly relative to said shaft assembly.

5. A mechanism according to claim 1 wherein at least a portion of said secondary shaft segment is of reduced diameter compared to said primary shaft segment.

6. A mechanism according to claim 1 wherein said first and second gear elements comprise mating first and second miter gears, respectively.

7. A mechanism according to claim 6 wherein said first miter gear is keyed to said secondary shaft segment.

8. A mechanism according to claim 1 including a plurality of primary shaft segments, wherein said at least one secondary shaft segment is coupled between two primary shaft segments.

9. A forming machine adapted to form a longitudinal margin of a strip of material into a desired profile, comprising:

A. a framework having side frames interconnected to one another by transverse members, said framework having an interior including a forming region through which said strip may be advanced from an upstream entrance to a downstream exit;

B. a drive mechanism disposed in the interior of said framework and operative to engage said strip and advance said strip in a downstream direction from said entrance to said exit;

C. an elongated rail structure mounted relative to said framework and spaced laterally from said drive mechanism, wherein said rail structure is comprised of an upstream rail structure and a downstream rail structure;

D. a plurality of forming elements secured to said rail structure to define at least one forming station that is positioned to receive said longitudinal margin and operative to contribute to forming said longitudinal margin into the desired profile as said strip is advanced through the forming region by said drive mechanism; and

E. a mechanism for adjusting a lateral distance between said rail structure and said drive mechanism, comprising:

an elongate shaft assembly, comprising:

i. an upstream portion, comprising:

a. at least one upstream primary shaft segment;

b. at least one upstream secondary shaft segment removably coupled to said upstream primary shaft segment, said upstream secondary shaft segment including a first upstream gear element disposed thereon;

c. at least one upstream projection shaft extending in a direction transverse to said elongate shaft assembly and including a second upstream gear element disposed on an upstream proximal end portion thereof, said second upstream gear element being coupled to said first upstream gear element whereby rotation of said elongate shaft assembly translates into rotation of said upstream projection shaft, said upstream projection shaft capable of being coupled to said upstream rail structure such that rotation of the upstream projection shaft operates to adjust the position of said upstream rail structure; and

d. an upstream support frame accommodating said upstream secondary shaft segment and said upstream proximal end portion; and

ii. a downstream portion, comprising:

a. at least one downstream primary shaft segment;

b. at least one downstream secondary shaft segment removably coupled to said downstream primary shaft segment, said downstream secondary shaft segment including a first downstream gear element disposed thereon; and

c. at least one downstream projection shaft extending in a direction transverse to said elongate shaft assembly and including a second downstream gear element disposed on a downstream proximal end portion thereof, said second downstream gear element being coupled to said first downstream gear element whereby rotation of said elongate shaft assembly translates into rotation of said downstream projection shaft, said downstream projection shaft capable of being coupled to said downstream rail structure such that rotation of the downstream protection shaft operates to adjust the position of said downstream rail structure; and

d. a downstream support frame accommodating said downstream secondary shaft segment and said downstream proximal end portion.

10. A forming machine according to claim 9 including a coupler interposed between said upstream and downstream portions, said coupler having a coupled state wherein said upstream and downstream portions operate concurrently, and a decoupled state wherein at least one of said upstream and downstream portions operates independently of the other.

11. In a metal forming machine adapted to bend a longitudinal margin of a strip of metal into a desired profile, including: a framework having side frames interconnected to one another by transverse members, said framework having an interior including a forming region through which said strip may be advanced from an upstream entrance to a downstream exit; a drive mechanism disposed in the interior of said framework and operative to engage said strip and advance said strip in a downstream direction from said entrance to said exit; an elongated rail structure mounted relative to said framework and spaced laterally from said drive mechanism, wherein said rail structure is composed of an upstream rail structure and a downstream rail structure; and a plurality of forming elements secured to said rail structure to define at least one forming station that is positioned to receive said longitudinal margin and operative to bend said longitudinal margin as said strip is advanced through the forming region by said drive mechanism, the improvement comprising:
