Processes:
Application of glues and adhesives:
The hot glue process, known as Hot Melt, consists of applying a fluid hot glue to a substrate with a coating head. In transfer coating, as in the animation above, or directly on the materials, this process allows good adhesion to the materials without having to carry out a drying phase. This process is well suited to the application of glue on materials in rolls. The adhesive materials resulting from the process are provided with a protector, paper or film, peeled before use by the customer. This process makes it possible to use permanent, fugitive, hot-reactivable adhesive glues, as well as with certain equipment, cross-linkable or reactive glues. |
Cutting:
Cutting by cutting lathe This process consists of cutting logs, small coils, of material up to 500mm in diameter, with lengths depending on the thickness of the material. The materials to be cut with this process are rolled up on a cardboard tube and attached to tube for sufficient support of the material during the cutting operation. Two types of equipment, with a rotating or fixed blade, make it possible to cut a wide range of materials. This process is well suited to plastic and elastomeric foam materials as well as nonwovens. |
Cutting by Press: This process consists of cutting materials with a cutting tool. The parts resulting from this process are in the shape of the tool. Depending on the equipment, the tool comes in: - a board fitted with cutting blades or punches inserted in the board, - an engraved cylinder or an engraved plate applied to a cylinder, whose revolution on the material generates the cutting of a shape. The process with a cutting board, called flat cutting, is suitable for a wide range of materials. The process with a cutting cylinder, called rotary cutting, makes it possible to cut a wide range of mainly adhesive materials and low thicknesses. |
Scroll cutting: This process consists of cutting materials with cutting blades applied to a counterpart. The blades are circular and the counterpart is generally cylindrical. The counterpart and/or the blades are driven in rotation. The material passes over a cutting counterpart to which blades are applied and is thus cut to the width set between the blades. Pressure is exerted between the counterpart and the blades to allow the cut. This cutting process is suitable for a very wide range of foam, elastomeric and non-woven materials. |
