Abstract

935,261. Making helically seamed tubing. E. K. MALKI, and V. SILDE. Sept. 4, 1961, No. 31701/61. Classes 83 (2) and 83 (4). [Also in Group XXVIII] A machine for making helically-seamed pipe comprises two rollers 1, 2 adapted to bear against each other and arranged to draw strip material 4 fed therebetween at an angle substantially a right angle relative to the axes of the rollers, a substantially annular guide means 10 with an inner diameter corresponding to the outer diameter of the pipe to be made and formed by a narrow support arranged to run in a convolution corresponding to the pitch of the helix into which the strip is to be bent and against which the rollers push the strip so that the latter is moved along the inner surface of the guide means and forms a ring, and a member 12 provided on the end of the guide means near to where the seaming takes place which is adapted to act on the strip coiling about the roller 1 in a manner such that the strip is helically bent for seaming. As shown, the strip material 4 is introduced between rollers after previously having the marginal edges preformed for mechanical interlocking. Along one side is a turned-up flange 5 and along the other side a folded-over flange 6 with a downwardly opening channel for accommodating the flange 5. The roller 2 has a groove 7 for accommodating the flange 5 and at the other end a seaming member 8 is provided, which cooperates with the lower roller to lock together the interengaging marginal edges of the strip. A bar 12 is secured to one end of the guide means so that a helical slot is formed at that end thereof, which guides the flange 5 on the strip so that it will mate in the channel in the folded-over flange 6. The rollers may function also as welding means. The strip material may be metal or plastic ribbon and the seam edges may be secured together by welding to provide an overlap joint or a butt-weld. If a pipe with an overlap joint is to be produced, the outer edge of the guide means has a helical shoulder inclined towards the roller which forces the strip to form a convolution.
