The application provides a movable apparatus for forming a thermo-softening part. The apparatus includes a first placement unit, a second placement unit, and a heat source. The first placement unit comprises one or more first rollers, which are movable in a first predetermined path. The second placement unit comprises one or more second rollers, which correspond to the first rollers. The second rollers are movable in a second predetermined path. The heat source is provided for heating an elongated thermo-softening material to a predetermined temperature. The first rollers and the second rollers are provided on opposite sides of the elongated thermo-softening material for compressing the thermo-softening material to form the thermo-softening material.

Freespace composite manufacturing process and device

A filter element () with a tubular folded bag () of folded filter material, which has a plurality of fold blades () adjacent each other in the longitudinal direction () of the folded bag () a closure cover () is attached at at least one axial end () of the folded bag (). In order to provide a filter element which can be bent to any desired curved form while maintaining a high degree of filtration performance, and can be produced in a cost effective manner, the fold blades () of a folded bag () are provided with a combination of diagonal folds extending at an angle relative to each other such that the fold blades () in the longitudinal direction () of the folded bag extend back and forth and thereby form a three-dimensional crown structure (). At least the outer margin of the closure cover () has a form corresponding to the crown structure () of the fold blades ().
