METHOD OF FORMING TUBULAR BODY AND MAKING TUBE FROM SUCH BODY Russian patent published in 2000 - IPC

FIELD: mechanical engineering. SUBSTANCE: invention relates to forming tubular body, particularly, multiple layer one, with at least one partition along its length forming adjacent longitudinal compartments and made of film tape 9. First strip 16' to form partition is secured on tape 9, or its cut-to-measured length or strip cut-to-measure length in parallel to tape 9 or its cut-to-measure length by means of outer edges 11 and then side edges are connected to form endless tube from which tubular bodies are cut off after-wards, or to form separate tubular body. Invention relates also to method of making tube from tubular body. According to this method tubular body is rigidly connected with head of tube containing bridges corresponding to location of partitions in tubular body and provided with at least one outlet hole closed by seal. EFFECT: possibility of easily making tubular bodies of arbitrary length. 14 cl, 9 dwg
