  • the apparatus according to the invention is very suitable for feeding the before mentioned strips in the production of the tubes.
  • the diameter of these tubes can be many meters.
  • One older known method is to produce tube using direct extruding when the produced tube does not rotate and it is moved during the production process length- wise.
  • the apparatuses to move tubes are produced for instance by Sica S.p.A:ssa (Internet: sica-italy.com).
  • fig 1 presents the apparatus according to the invention, seen directly from above, fig 2, presents the above mentioned apparatus seen directly from a side, from the direction A in fig 1,

  • the perpendicular cross section of the tube means in these application documents the cross section of the tube that is in the right angle with the geometric middle axis 101.1 of the tube in question.
  • the chain 2 means in the documents of this application and especially in the claims in addition to the actual chain also belt and other for power transmission suitable endless, that is looping thing Following is an explanation of one for invention advantageous structure and operations referring to the before mentioned figures.
  • FIG.l there is shown directly from above an apparatus 1 according to the invention being used in a solution according to the invention where the apparatus has been in- stalled to the connection of a plastic tube 100 that is in production process.
  • Fig. 2 presents the same situation directly from a side, that is seen from the direction A in fig. 1.
  • There is an endless chain 2 under the tube 100 which chain has been set to go round upon the drive wheel 3 and the sheave 4 and it is also set to go round the tube 100 once when advancing from the sheave to the drive wheel.
  • the drive wheel 3 is the distance H ahead the sheave 4 in the moving direction x of the tube, that is the center points of the above mentioned wheels have axes where the perpendicular cross sections of these axes are the distance of H from each other when measured normally.
  • the part 2.1 of the chain coming from the sheave 4 and going under the tube 100 and on the other hand the direction w of the part 2.2 of the chain coming under tube and going to the drive wheel 3 is angle a to the moving direction x when compared to the vertical cross section.
  • Chain 2 goes from the drive wheel 3 towards the sheave 4 under it to the first return guide 5 parallel to the direction that it comes to the drive wheel 3, that is in right angle with the axis 3.1 of the drive wheel and makes a turn at the point of this return guide and advances thereafter directly all the way to the other return guide 6.
  • the chain turns again into a new direction and advances from there to the sheave 4 parallel the direction it goes from sheave under the tube 100 up to the first point A, which is in right angle with the axis 4.1 of the sheave.
  • the part of the chain that is under the sheave and the drive wheel has been marked 2.4.
  • the chain turns to advance around the tube 100 following the helical line the pitch N of which (line AB) is equal to the pitch of the helical line of the tube 100 that is to be produced, that is the advancement of the joint in one rotation.
  • the type of the chain 2 is sideward folding and so the changes of the direction in the return guides are possible. For instance under the product name "Uni-Chain” marketed chains were very suitable for this purpose.
  • the return guides 5, 6 are in this example rolls that have been supported to the vertical position and they rotate around their axes by the movement of the chain 2 leaning against them and keep the chain in the above described position.
  • the starting tube 101 is put backwards close to the form where it is joined to the melted mass that comes out of the extruder to the core and melted mass that is in the form upon the core and comes out from there.
  • the gripping surface of the starting tube that is its end face has been preheated in order to make possible that the starting tube and the melted mass get welded to each other.
  • the core 103 is rotated with its own rotating equipment and at the same time one starts to rotate the starting tube 101 using the apparatus 1 according to the invention. In this phase the welding joint is cooled so that it would stand the lengthwise movement of the tube using the apparatus 1.
  • the rotating speeds of these equipments are set essentially to same speed and their speed will be raised at the same time so much that the desired speed of tube production is achieved.
  • the chain 2 has been tightened using the tightener 7 so much that the friction parts 8 bite close to the surface of the starting tube.
  • the chain 2 that advances upon the drive wheel 3 and the sheave 4 start rotating the starting tube 101 and the tube 100 that is fixed to it and starts to form with the same speed as the raw material is fed from the extruder through the nozzles 102 on the core 103 that is suitable to the inside diameter &
  • the width L of the raw material flow 104 coming out of the nozzles 102 is sufficient for forming the tube during one rotation of the tube, either a butt joint or an overlapping joint can be used.
  • the pitch N (line AB) is thus also the pitch of the spiral joint of the tube 100.
  • the first supports 9 support the chain 2 sideways so that its sideways advancement into the direction x takes place with a constant speed and the other support 10 supports the tube 100 so that it keeps its position in the lateral direction zl - z2.
  • the chain 2 moves upon the tube 100 and moves it in the same way into the direction x as before the starting tube 101 so long as the production of the tube 100 continues.
  • the feeding of the material from the extruders is terminated and the apparatus 1 is stopped.
  • the apparatus 1 is dimensioned so strong and steady that the chain 2 is able to hold up also that part of the tube that is in the operation area of the apparatus 1 and near it.
  • additional supports are also needed to hold up the tube.
  • the distance H is always tuned to be suitable with the outside diameter D of the tube 100 and the pitch N of the spiral weld.
  • the idea of the invention is realized always when the friction between the surface of the tube 100 and the chain 2 becomes by the manner that has been described before so great that there is no slide between the tube and the chain when rotating the tube during the produc- tion process.
  • the idea of the invention is also realized with an incomplete round but the realization in practice with the other ranges of rotation than the full rotations is more complicated.
  • the friction parts 8 that are fixed to the chain can be for instance rubber and their re- lational amount can be adopted to correspond to the characteristics of the tube to be produced.
  • the return guides 5, 6 can be for instance rolls or slide guides.
  • the apparatus 1 according to the invention can be done adjustable so that its parts like drive wheel 3, sheave 4, return guides 5, 6 and the supports 9, 10 can be located in suitable places according to the diameter of the tube 100 and the pitch of the spiral-weld.
  • the rotation speed of the drive wheel 3 can also be changed as the situation requires.
  • the chain 2 can also be done in a way that is suitable to the situation, e.g. each chain operates in certain size range of the tube 100 and the pitch range of the spiral-weld.
  • the method according to the invention can also be done so that the apparatus 1 according to the invention does not include the return guides 5, 6.
  • This kind of situation has been described in fig. 3.
  • the chain 2 goes from the drive wheel 3 directly to the sheave and the axes of these wheels are installed advantageously pointing in different directions with each other so that the chain stays on these wheels.
  • the chain 2 goes round its circumference the longitudinal axes of its parts 2.1 and 2.2 keep pointing to the same direction and the chain stays on the drive wheel and sheave in balance state in relation to the lengthwise direction of their axes.
  • the method and the apparatus according to the invention are very suitable to produce spiral-welded plastic tube, but they can also be used to produce tube of some other material than plastic. For instance glass fiber, carbon fiber or some metal can be used to produce tube with this method and apparatus. And also the combination of the before mentioned materials can be used as the raw material of the tube 100.
  • the apparatus 1 When the apparatus 1 is used to produce spiral-weld plastic tube in feeding material (fig. 4), the material strip or strips and melted plastic material 104 is fed upon the part 2.1 of the chain. Thereafter, the material advances upon the chain to the core 103 and goes round the core between it and the chain 2 advancing with every rotation the distance of the pitch N to the direction x. Between the rounds that wind on the core, a joint is formed that follow the helical line where the material wind rounds get welded together forming thus the tube 100.
  • the apparatus 1 can operate only as a material feeder or it can also perform the rotation of the core and the tube and the sideways movement of the tube either alone or as a help of another power device.
