Definitions
- the invention relates to a spool for winding a fibrous web comprising a spool core with a, the lateral surface of the spool forming coating.
- the reels are predominantly covered with a rubber layer.
- the entire fibrous web or a strip thereof is discharged into the pulper in the machine cellar.
- the fibrous web is passed to the carrier drum to a scraper of the same.
- the object of the invention is to improve the winding and unwinding of the fibrous web and the winding quality.
- the object has been achieved in that the outer circumferential surface of a plurality of axially juxtaposed, separate coatings is formed, of which at least two adjacent coatings are made of different materials.
- the coating can be better adapted to the requirements of the winding process.
- the lateral surface of the main drum is also formed by three coatings arranged axially next to one another.
- the axial length of one or the average coating should be between 10 and 200 cm, preferably between 30 and 100 cm.
- one or the axially middle coating has a smoother surface than the outer coatings. Due to the higher adhesion, the adhesion of the tip of the fibrous web at the beginning of the winding is to be strengthened.
- the tip which is usually glued on when the tambour is unrolled can also be removed more easily from the tambour.
- the roughness R a of the smoother, middle coating should preferably be less than 0.2 ⁇ m.
- a roughness R a of 0.6 ⁇ or more is sufficient.
- At least one, preferably an axially middle, coating should consist at least partially of Teflon.
- the entire coating may consist of Teflon. But it may also be advantageous if a tape, in particular a fabric tape is coated with Teflon and forms the coating. Furthermore, it is additionally or alternatively advantageous if one or the axially middle coating has a higher elasticity than the axially outer coatings.
- the tip of the fibrous web can be pressed more easily into the coating of the spool during winding. This prevents that the tip of the fibrous web is imaged in the subsequently wound fibrous web and leads there to markings.
- Production is particularly simple if one or the axially middle coating is supported directly on the spool core.
- one or the axially middle coating may be embedded in a coating extending over the entire axial extension of the spool core.
- the application of one or the middle coating can be facilitated if it is formed by a fabric band.
- FIGS. 4-7 a cross section through differently coated tambourines 1.
- the fibrous web 2 is wound on a spool 1 in the form of a spool core 3 made of steel with in particular rubber or plastic coating.
- the drum 1 is driven at its circumference by a carrier drum 8.
- the fibrous web 2 can be separated in different ways. In most cases, the separation and the application of the fibrous web 2 to the empty spool 1 carried out with the assistance of an air or water jet.
- the scraper 9 separates the fibrous web 2 or the corresponding strip from the lateral surface of the carrier drum 8 and then directs it down into the machine cellar.
- the outer circumferential surface of the spool 1 is formed by three circumferentially encircling and axially juxtaposed coatings 4,5.
- the central coating 5 has an extent in the axial direction between 30 and 100 cm.
- this tip of the fibrous web 2 is usually provided with adhesive.
- the axial, middle coating 5 is formed by a Teflon adhesive tape embedded in the axially continuous coating 4 of hard PU or rubber. Accordingly, this continuous coating 4 also forms the two axially lateral coatings 4 of the lateral surface.
- the Teflon adhesive tape can be easily wound on an axially central recess in the continuous coating 4. Because of the smoother in comparison to the side coatings 4 surface of the Teflon adhesive tape, the tip of the fibrous web 2 adheres much more to the outer surface of the spool 1 during Anwickeln.
- the frequently glued-on tip of the fibrous web 1 can be more easily detached from the tambour 1 during unwinding.
- the axially middle coating 5 in the form of a Teflon adhesive tape according to FIG. 7 can also be applied to the axially continuous coating 4 made of hard PU or rubber, in particular adhesively bonded.
- the axially middle coating 5 projects slightly beyond the adjacent coatings 4 by 0.05 to 0.25 mm, which, however, does not affect the winding quality.
- the axially middle coating 5 in the embodiment according to FIG. 5 is formed by two radially superimposed layers 6, 7. While the radially outer layer 6 is again formed by a smooth Teflon adhesive tape to form a smooth outer surface, the radially inner layer 7 consists of a PU tape with silicone coating. This radially inner layer 7 is substantially more elastic than the radially overlying layer 6 and the axially continuous coating 4 of the spool core 3.
- the tip of the fibrous web 2 can thus be pressed into the tambour 2 more easily during winding, so that this tip does not form in the wound-up fibrous web 1 and leads to markings.
- the middle coating 5 is applied directly to the spool core 3.
- the middle coating 5 may be more elastic than and / or have a smoother outer surface than the two lateral coatings 4.
- the axially middle coating 5, as in FIG. 7, has a larger outside diameter than the axially outer coatings 4.
- the larger diameter ensures reliable and intensive gap formation with the carrier drum 8 for stronger pressing of the tip of the fibrous web 2 secured to the spool 1 when winding.
- the transition from the smaller diameter of the side coatings 4 to the larger diameter of the middle coating 5 should be gradual.
- the diameter of the central coating 5 is here only 0.1 to 2 mm larger than the diameter of the lateral coatings 4.
- the thickness of the, embedded in the axially continuous coating 4, the central coating 5 is between 0.1 and 5 mm, in particular between 0.1 to 2.5 mm.
- the total thickness of the coatings 4, 5 on the spool core 3 is 5-20 mm.
