Vertical edge bite synthesis machine

The edge biting forming machine can process metal coils or sheets such as aluminum alloy plates, galvanized steel plates, stainless steel plates, etc. through processes such as unwinding, leveling, progressive rolling, biting forming, and fixed length cutting, to produce various specifications of roof panels such as high and low edges.

1、 Core concept: What is vertical bite?

Before understanding machines, it is necessary to first comprehend the core concept of 'Standing Seam'.

Definition: It is a roofing system connection process that uses specialized machinery to interlock the upright rolled edges of adjacent metal roof panels, and then uses a locking machine for secondary locking to form a high-strength, weatherproof continuous seam.

Form: The final seam formed is upright on the roof, hence the name 'standing edge'.

Difference from traditional boards: Unlike the method of fixing the board surface with self tapping screws, the vertical edge bite is a non perforated connection.

The vertical edge biting synthesis machine is specifically designed for producing metal roof panels with vertical rolled edges.

2、 The main components of the equipment

A complete production line for edge biting plywood includes:

Material discharge system: carrying metal coils (usually aluminum magnesium manganese alloy plates, aluminum zinc plated plates).

Leveling system: Ensure that the incoming board is straight.

Molding host (core):

Composed of multiple precision rolling rolls, the ultimate goal is not to form wave peaks on the plate surface, but to form complex male and female ribs for interlocking on both sides of the plate.

The common rib is usually a simple standing edge with a small hook.

The female rib is a more complex vertical edge with internal slots for the male rib to hook onto.

Fixed length cutting system: Cut the roof panel with male and female ribs into the required length.

Electronic control system: controls the operation of the entire line.

3、 Key features and advantages of the vertical bite system

Excellent anti leakage performance:

No perforation: The entire roof has no screws penetrating the panels, fundamentally eliminating the risk of water leakage.

Strong sealing: The bite joint is tightly combined and then locked to effectively prevent the infiltration of wind and rain.

Excellent structural performance:

Strong wind resistance: The unique interlocking structure forms a whole roof, which can withstand extremely strong negative wind pressure (preferred in typhoon areas).

Adapt to thermal expansion and contraction: The board can slide freely on a fixed support, releasing stress caused by temperature changes and avoiding structural damage.

Durability and aesthetics:

Due to the absence of screw holes, the board has no corrosion starting point and a longer service life.

The roof lines are smooth and neat, with a modern and atmospheric appearance.

4、 Workflow: From molding to installation

The completion of the edge biting system requires two steps, corresponding to two types of machines:

Step 1: Panel Forming

Equipment used: Vertical edge bite synthesis machine.

Process: In the factory, the coil is passed through a forming machine to roll out roof panels with male and female ribs, and then cut to a fixed length. Then transport it to the construction site.

Step 2: Lock the edges on site

Equipment used: handheld electric edge banding machine or automatic walking edge banding machine.

Process:

Lay the prefabricated roof panels on the roof structure with fixed supports.

Insert the male ribs of adjacent panels into the female ribs and engage them initially.

Use a locking machine to clamp the vertical edge, move it longitudinally along the roof panel, and tightly lock and press the male and female ribs together to form a firm vertical seam.
