  • reference numeral 39 depicts a ring shaped or annular matrix into which prior to commencement of the pressing operation a mandrel 20 is entered into carrying a body 11 and head 12 and a material portion 17 , whereby the end of the pressing operation is shown in FIG. 6 .
  • the matrix 39 (shown only in schematic form) can have an inner ring 40 spring biased and movable in the direction of movement of mandrel 20 , which ring serves as a hold down device for the head 12 upon mandrel 20 and which serves with its outer diameter as an axially movable moulding wall and resting upon the shoulder 14 will form for instance the inner running round demarcation 28 .
  • the moulding contour of matrix 39 is being formed by a cylindrical section 41 and a radius formed section 42 .
  • the inner diameter of cylindrical section 41 corresponds to the outer diameter of mandrel 20 with body 11 arranged thereon.
  • the radius formed section 42 is dimensioned in such a way that is moulds the backward part of the annular section 22 as round or radius formed transition from body 11 to head 12 while its forward part during the pressing operation is brought into contact with the outer surface of the shoulder 14 .
  • the method to connect a prefabricated head 12 with a body 11 by means of forming a ring like connection or seam upon the shoulder 14 of head 12 is operated essentially in six partial steps.
  • the first partial step is loading mandrel 20 with a body 11 in such a way that an annular section 22 of body 11 extends beyond the transition 23 of mandrel slope 24 to outer circumference 25 of mandrel 20 .
  • the axial dimension of annular section 22 depends upon the radial distance which the freely running round edge 26 of section 22 , which edge 26 forms the outer running round demarcation 28 , is designed to show after the pressing operation.
  • Increasing the length of section 22 means that the position of the outer running round demarcation 28 moves up toward the outlet 16 while decreasing its length means the outer running round demarcation 28 would move down toward the transition 23 that means towards the outer circumference of mandrel slope 24 .
  • a prefabricated head is arranged upon the mandrel whereby it is arranged thereon by way of the opening of outlet 16 and mandrel extension 21 and in that position the head 12 is being surrounded by the axially extended section 22 .
  • the material portion 17 of connecting material is deposited upon the visible outer surface of shoulder 14 . It is preferred that the material portion 17 rests against the inner circumference or surface of the annular section 22 completely running around said surface.
  • the material portion 17 consists of a plasticized plastic the composition of which is to be selected in such a way that it connects itself with upon application of pressure and if necessary heat with the plastic of the head 12 and that of the body 11 in case a laminate is used with the inner plastic layer of body 11 .
  • the material portion 17 can be deposited into the die in prefabricated form or extruded upon shoulder 14 preferably covering the annular rooms 35 .
  • Preferred a material portions 17 shaped ring like that means as closed rings and the cross-section thereof is preferable of circular, lenticular or drop like configuration.
  • the plastic material of portion 17 has a different colour which is significantly different from the colour of the plastic material of the head and if so desired from the colour of the body 11 .
  • head 12 and portion 17 enter into the open annular matrix 39 .
  • an inner ring 40 the outer surface of the shoulder 14 gets into contact with the inner ring 40 and moves same during the entering movement of mandrel 20 into the matrix 39 against it's spring biased resistance.
  • the pressing and forming of the feature 15 is effected.
  • the material portion 17 is pressed into annular room 35 , stepped arrangement 29 and into the first 32 and second 33 chambers of multi-chamber stepped arrangement 31 connecting head 12 and body 11 at the same time bending the annular section 22 in direction of the outer surface of shoulder 14 .
  • the pressing operation is finished when the inner surface of section 22 abutts or is in contact with the outer surface of shoulder 14 .
  • part of the material potion 17 is being pressed and flowing by way of the annular section 22 in direction of the outlet 16 until the plastic squeezed over the surface of the shoulder 14 runs or flows against the upward directed surface 30 of the stepped arrangement 29 or flows against the outer circumference of inner ring 40 .
  • the connection of body 11 and head 12 is effected, the annular section 22 is by means of the plastic of portion 17 squeezed in direction of outlet 16 connected to the shoulder 14 and a ring formed feature 15 on shoulder 14 is formed in a distance encircling the outlet 16 , which feature is formed by an inner 28 and outer 27 demarcation circulating upon the outer surface of shoulder 14 means (upward directed surface 30 , inner ring 40 ) forming the inner encirculating demarcation 28 are preferred for a precise configuration of feature 15 , it is however possible to let the plastic material flowing in front of the freely running round edge 26 (forming the outer edge of the ring) to flow freely, that means without the means mentioned above over the outer surface of shoulder 14 .
  • mandrel 20 with tube 10 is moved out of matrix 39 , tube 10 is ejected from mandrel 20 whereupon the method to manufacture a tube with feature 15 can be repeated.
