摘要： AN APPARATUS FOR STRIPPING FLEXIBLE TUBES FROM MANDRELS ON WHICH THEY ARE CURED. THE BOND AT THE INTERFACE BETWEEN THE TUBE AND THE MANDREL IS BROKEN BY INJECTING A LIQUID AT HIGH PRESSURE INTO THE INTERFACE WHILE SIMULTANEOUSLY MASSAGING THE OUTER SURFACE OF THE TUBE. ONCE THE BOND IS BROKEN, IT IS POSSIBLE TO AXIALLY DISPLACE THE MANDREL WITH A PNEUMATIC RAM.

摘要： TUBE CUTTING APPARATUS Disclosed is an apparatus for cutting elongated tubular material into short individual sections. The apparatus comprises a plurality of circular knives fixedly mounted in spaced relationship to each other along the axis of a nonrotating shaft. Rotatable spacing discs having a diameter slightly greater than the diameter of the knives are mounted one on each end of the knife-carrying shaft and are adapted to engage the bare end portions of a rotatable mandrel having a tube to be cut thereon when the knives are moved into cutting engagement with the tube. The rotatable spacing discs riding on the rotatable tube-carrying mandrel prevent the knives from cutting completely through the tube wall and make possible the retention of very thin, frangible, residual tube wall sections of precise constant thickness at the locations of the cuts. This allows the tube to be removed from the mandrel in one piece and then broken later, if desired, into individual short sections by hand or machine.

摘要： 1324516 Stripping tubes from mandrels ARMSTRONG CORK CO 31 July 1970 [1 Aug 1969] 37168/70 Heading F2P Apparatus for stripping tubes from mandrels comprises means for injecting a fluid at high pressure into the interface between the tube and the mandrel, means for massaging the outer surface of the tube on the mandrel and means for effecting relative lateral displacement of the tube and mandrel. As shown, tubes 10 on mandrels 12 are fed, by conveyer means, intermittently to stripping apparatus 16. Each tube operates a cycle actuating switch 26 on its way to the valley between drive roll 32 and eject roll 34. When the tube is in position, top roll 48 descends so that the tube on the mandrel is massaged between the rolls 32, 34 and 48. High pressure fluid is injected from the pivoted nozzle 58 at the end of the tube to the interface 62 between the tube and the mandrel which with the massaging effect of the rollers loosens the tube from the mandrel. An axially moving ram (72) (Fig. 1, not shown) is then operated to push the mandrel out of the tube whilst the latter is held axially by the rolls. The mandrel is fed away by rolls (100). Roller 34 is then moved to the dotted line position 110 and the ram (72) retracted so that the tube 10 falls into trough 112. The relative positions of the rolls 32, 34, 38 and the ram 72 are adjustable for different sizes of tubes and the nozzle 58 is so pivoted at 64 that it will always contact the underside of mandrel 12.
