What is it and what does it do?

Imagine you’re making a layered pastry, like a croissant. You need to repeatedly fold and layer the dough to create those delicate, flaky layers. A clamping lapper does something similar with a web of fibers in non-woven manufacturing.

Its main job is to take a continuous web of fibers (usually from a carding machine) and fold it back and forth in a very specific way to create a thicker, layered web. This layered web is then used in the next steps of the non-woven process.

How is it done?

Clamping lappers use a combination of belts, rollers, and a “clamping” mechanism to achieve this folding:

1. Infeed: The web of fibers is fed into the clamping lapper.
2. Clamping: The “clamping” part involves two belts or surfaces that come together, “clamping” the web and holding it in place.
3. Folding & Layering: Other belts or rollers then move and fold the web back and forth, creating a series of layers. The way these belts move determines how the web is folded (e.g., into a “z” shape or other patterns).
4. Delivery: The layered web is delivered out of the machine, ready for the next step in the non-woven process.

Use in the Non-Woven Sector

Clamping lappers are used in non-woven manufacturing when you need:

1. Specific Web Structure: They create a layered web with a particular fold pattern, which can affect the final properties of the non-woven fabric (like its strength and how it drapes).
2. Thickening the Web: By repeatedly folding the web, they increase its thickness and weight.
3. Preparing for Bonding: The layered web created by a clamping lapper is often an intermediate step before the non-woven material is bonded together using techniques like needle punching, thermal bonding, or chemical bonding.

Think of it this way:

Imagine folding a piece of paper like a fan. Each fold creates a layer, and the more folds you make, the thicker the fan becomes. A clamping lapper does something similar with the fiber web, folding it in a precise and automated way.

In short, the clamping lapper is a specialized machine for creating layered fiber webs with specific fold patterns. It’s a key part of producing certain types of non-woven materials, especially those requiring a particular structure or thickness.
