DEVICE FOR THE CONTINUOUS PRODUCTION OF CURVILINEAR PIPES OF COMPOSITE MATERIALS Russian patent published in 1995 - IPC

FIELD: manufacture of building materials. SUBSTANCE: device has biorne foundation 1, mandrel consisting of movable 2 and immovable 2 sections connected by opposite springs 10, the mechanism for shifting movable section 3 made in the form of cylinders 7 and rods 9 hinged correspondingly with sections 2 and 3 of the mandrel, stacker 4 of the glass band with bobbins 6 assembled on the face end of movable section 3, polymerization chamber 33, cut-off device 34 and tracking means for the mutual arrangement of sections 2 and 3 of the mandrel. The tracking means have displacement transducers 22 made with the possible contact with stationary disk 21 carrying immovable section 2 of the mandrel fastened cantilevered. Transducers 22 are mechanically and electrically connected with controlled stopping devices 18 of the mechanisms for the reciprocal displacement of bobbins 6. The stacker of glass band 4 is mounted on the face end of movable section 3 of the mandrel. The device ensures the amplitude change of the glass band placement depending on the form of the article to be produced. The innovation on the concerns the equipment for reeling curvilinear pipes. EFFECT: enhanced quality of the pipe production due to the amplitude change of the glass band placement and the junction overlapping. 6 dwg
