Façade cassettespro

Sloped triangular cassette

A single flat, tilted face: one side in the wall plane, the tip raised — or the reverse. Laid head to tail, point up then point down, they form a sawtooth façade that catches the light row by row, with no waste between parts.

Fabrication data

Sloped triangular cassette — at 700 × 606 mm in 4 mm ACM, this family unfolds into a 770 × 721.8 mm flat pattern with 6 folds, all grooved from the back: no pass on the coated face. A 1,500 × 3,200 mm sheet holds 8 of them, for 32.5 % waste.

Manufacturing constraints

  1. The return must exceed the groove width plus half the bend deduction, or the groove eats into the return.
  2. Facet-to-facet folds are grooved with the smallest cutter of the profile, V left open: the angle is held by the geometry. The angle between two facets must not exceed that cutter’s apex angle.
  3. Vertical returns, all tabs flat in the −D plane (rail mounting). The facet-to-return fold is 90° ± slope: below 90°, the 90° cutter is left open and the return is held by the riveted tab; above 90° (facet descending towards the edge), a wider cutter (60° nominal = 120° apex) or the machine profile’s overfold tolerance is needed.
  4. Every raised vertex requires a V-slit to the edge (a flat sheet has 360°, the relief less). Near the vertex the slit is narrower than the contour tool: it is cut along its axis and the tool bites each facet by up to Ø/2.
  5. Tabs are shortened at every corner and every kink of the edge so they never collide behind the panel: by (return + 2 mm), and more on a sharp corner, where the bisector must be cleared (tab width ÷ tan(angle/2)). An edge too short gets no tab.
  6. The face stays perfectly flat: three vertices always define a plane, whatever the height. All of the relief is carried by the returns, whose height runs from zero at the wall plane to the full lift.
  7. At the highest point the return keeps at least 15 mm beyond the lift, so the tab still bears on the framing. A steep slope therefore needs a deeper return.
