Definitions
- the invention relates to a winding tube for winding Tapes, foils or sheets made of plastic, paper, metal or the like and a method of manufacturing a such a winding tube.
- the invention is therefore based on the object To create a winding tube that is relatively lightweight, very high radial strength and bending stiffness and is easily recyclable.
- the form of a corrugated tube wound winding tube so wound is that the tape turns are at least half of theirs Bandwidth overlap and thus an at least two-layer Form tube wall. If a particularly wall and bending resistant If the winding tube is desired, the tape windings should turn around 2/3, 3/4 or more of their bandwidth overlap and thus one form a three-layer, four-layer or multi-layer pipe wall.
- longitudinally corrugated or longitudinally ribbed is understood that the longitudinal extension of the waves or the ribs in Longitudinal direction of the tape runs.
- the waves of the tube in the Cross-section are trapezoidal. It is also expedient that the Tube heads located outside the tube are wider than that shaft feet on the inside. To increase the bending stiffness, the butt welded shaft heads together, be soldered or glued.
- the winding tube can be made of foils or tapes Be made of aluminum, steel or copper. This can it may be advantageous if the material of the winding tube is is the same as that of the film to be wound or winding tape. In this case, those on the Wrapping sleeve possibly remaining ends of the on the Sleeve of wound tape or film can be recycled together with the winding tube.
- corrugated pipes made with longitudinally corrugated metal strips tape wraps overlapping at their edges, including those with flattened outer wave crests, known (e.g. DE 2 235 012 A).
- these known corrugated pipes serve as Line pipes for the line of primarily gaseous Media, such as pipes in ventilation and air conditioning systems or the like, but not for the production of Winding sleeves for winding tapes, foils or sheets made of plastic, paper, metal or the like.
- corrugated pipes that are not made by winding one longitudinally corrugated tape are made, but by Extrusion, blow molding or upsetting rolls (e.g. EP 0 474 449 A2). Due to their curl, i.e. through the im Longitudinal section of wall of different thickness can be made these tubes have a great deal of flexibility at the same time obtained high radial compressive strength, so that with them Pipe curvatures can be created like this pressure-resistant pipelines is often necessary.
- the waves of the aforementioned, not by winding The corrugated pipe produced can have a triangular cross section and have flattened outer and inner shaft heads, wherein them with the corresponding heads of the neighboring waves can collide. This is said to despite the pipe great flexibility, the smoothest possible inner surface be awarded what a turbulence-free flow in the Pipe is highly desirable.
- the one shown in FIG serve schematically illustrated device.
- the device is the metal strip 8 drawn off from a coil 7 passed through pairs of guide and forming rollers 9, the desired longitudinal corrugation of the tape according to FIGS. 6 and 9 give.
- the longitudinally corrugated band 10 then runs into a A winder, the one shown in Fig. 11
- Example of a winding mandrel 12 rotatable about its axis 11 and arranged on the circumference of this winding mandrel and Winding rollers 13, 14 is formed.
- Mandrel 12 and rollers 13, 14 can one of the longitudinal corrugation or longitudinal ribbing of the tape have appropriate profiling.
- the tape is wound helically around the mandrel 12, whereby the waves or ribs of the thereby formed adjacent tape wrap in the area of the overlap interlock.
- Fig. 12 shows a winding device, the two each other has opposite inlet and connecting rollers 15, 16, between which the previously corrugated or ribbed Band 10 runs through. Then this volume is through a bending roller 17 is given a bend, causing the tape with further guidance by guide rollers 18 to the tube is formed.
- the flat pressing and widening of the outer and inner shaft heads 1, 2 are made by pressure rollers 15 ', 16', i.e. between two rollers on one of the Entry point into the winding device following the point are arranged. It also leads to a framework-like Stiffening the pipe wall, giving the pipe its flexibility loses. It becomes a light, rigid pipe with through Get cross ribs stiffened double wall, of which each cut the length of the desired winding tube can be.
