METHOD AND APPARATUS FOR PRODUCING A TUBE PARTIALLY HAVING A NON-CIRCULAR CROSS SECTION AND HAVING CIRCULAR END PORTIONS AND USE THEREOF |
摘要 |
Disclosed is a method for the production of a tube having, in sections, a non-circular profile by deforming, comprising:
a) providing a tube, which has a circular initial profile;b) conveying the tube in a hot, malleable state through a nip, which is formed by squeezing rollers and has a first nip width, which is larger than or equal to an outer dimension of the initial profile;c) adjusting the squeezing rollers for setting a second nip width, which is smaller than the outer dimension of the initial profile, and deforming the initial profile in said hot, malleable state for obtaining said non-circular cross section; andd) adjusting the squeezing rollers for setting a third nip width, which is larger than or equal to the outer dimension of the initial profile, and severing said tube in a region having a circular cross section;so that respective end portions of said tube have a circular cross section;According to the invention, the tubes can be connected reliably with connecting-members or other tubes via the end portions having the circular profile using proven tube connection technologies. At the same time there is at least one central section having a non-circular cross section which is of advantage, for example for applications in photobioreactors. |

a) providing a tube, which has a circular initial profile; b) conveying the tube in a hot, malleable state through a nip, which is formed by squeezing rollers and has a first nip width, which is larger than or equal to an outer dimension of the initial profile; c) adjusting the squeezing rollers for setting a second nip width, which is smaller than the outer dimension of the initial profile, and deforming the initial profile in said hot, malleable state for obtaining said non-circular cross section; and d) adjusting the squeezing rollers for setting a third nip width, which is larger than or equal to the outer dimension of the initial profile, and severing said tube in a region having a circular cross section; so that respective end portions of said tube have a circular cross section. |
