 Gutter Machine Terminology

GUTTER MACHINE TERMINOLOGY 

 

Entry end - the end of the gutter machine into which the material is fed, the end with the black curved guides; also called the front end or feed end.

Exit end - the end of the gutter machine from which the finished gutter profile emerges,  the end with the shear; also called the rear end or discharge end.

Forming rolls - the rotating contoured dies used to both drive the material through the gutter machine and form the finished gutter profile; also called forming dies, rolling dies, rollers. 

Left side - when viewing from the entry end of the gutter machine, the side located to the left. 

Right side - when viewing from the entry end of the gutter machine, the side located to the right. Also called the "Box Side". 

Station # - forming stations are numbered sequentially from the entry end to the exit end of the gutter machine. 

Crash - a condition in which any of the following problems may exist: 

- metal will not move through the gutter machine

- metal is bent or crumpled against a fixed component in the gutter machine

- metal is bunching up between forming stations

- the drive train is seized

PROFILE SPECIFIC TERMS:

The profile is normally described as if it were being viewed from the entry end of the gutter machine as the

material runs:

Away from the house - profile is horizontally level, but curves toward the front, or box side, of the gutter.

Downhill - the profile runs laterally strait, but curves downward as it exits the gutter machine; also referred to as having a crown in the profile.

Into the house - profile is horizontally level, but curves toward the backside of the gutter.

Left - the profile is horizontally level, but curves to the left as it exits the gutter machine.

Right - the profile is horizontally level, but curves to the right as it exits the gutter machine.

Twist - one end of the profile rotates away from the other end.

Uphill - the profile runs laterally strait, but curves upward as it exits the gutter machine.

MATERIAL/COIL RELATED TERMS:

Camber - lateral curvature in coil stock - camber may lead to an inconsistent profile.

Coil Set - longitudinal curvature induced in coil stock due to the winding or coiling process - excessive coil

set may cause rippling in the gutter profile.

Edge wave - a ripple-like effect on the edge of the material - often caused by the slitting process.

Gauge - term used to reference the thickness of steel material per AISI thickness tolerance ranges - ex: 24

Ga = .0276" thick

Long-centered - center of the coil stock strip slightly longer than the edges - often results from the

Heating and cooling process

Oil canning - a periodic pattern of buckling appearing on flat sections of a profile - often results from coil

Set.

Width - the lateral width of coil stock material - also called strip width or stretch-out.

UNITS:

Standard Units:

in - inches (unit of length)

lbs - pounds (unit of weight)
