Abstract
A method and a device for scrap-free manufacture of coated profiles and thermoformed containers. A hollow pipe having a cross-section suitable for the desired profile is extruded. The extruded hollow profile is cut longitudinally. Thereafter the profile is planar laminated by a web formed material having desired characteristics. The cut, laminated profile thereafter is formed into the original shape thereof, or another suitable shape, and is formed into container casings. When thermoforming containers, a hollow profile is extruded from a thermoformable material in an extruder, this hollow profile is cut, in one or several longitudinal cuts. In web or roller form such cut profile is supplied to a so called scrap-free thermoforming machinery, where the thermoformed containers are manufactured.
