359,935. Making paper milk &c. vessels. FARROW, T., Victoria Mills, Ryecroft Street, Ashton-under-Lyne. July 28, 1930, No. 22642. Addition to 328,765, [Class 60, Grinding or abrading &c.]. [Classes 18 and 66.] Relates to a machine for making the tubular bodies of paper milk &c. vessels, of the form shown in Fig. 7, from conical tubes previously wound on mandrels. The wound tubes are placed on one of a number of rotatable mandrels E, Figs. 8 and 10, mounted in bearings in a headstock D intermittently rotated as in the parent case ; the mandrel spindles carry gear wheels e<3> one of which is engaged by a continuously rotating wheel k, at each dwell of the headstock. A tube A<1> being placed in position on a mandrel during a dwell of the headstock (position 1, Fig. 10) first becomes carried opposite to a revolving tool H (position 2), the mandrel at this station being held from movement by a spring or bracket J<1> engaging the pinion e<3>. The tool, which is brought up to the mandrel by an oscillating lever G<2> controlled by a rod G<3> operated as in the parent case, has a part h, Fig. 13, which enters and shapes the end of the tube into cylindrical form, and a series of inclined pins or pegs g<1>, Fig. 14, which turn over the end to form the rim a<4>. The mandrel next passes to position 3 where it is caused to revolve by the action of the wheel k and is engaged by pairs of grooving discs J; or passes between fluted or grooved rollers, by which the grooves a<1>, a<3> are formed, the mandrel being meanwhile engaged by a slidably mounted loose spindle F, Figs. 15 and 16, controlled by a camoperated forked lever F2, the end of which spindle has teeth f adapted to engage teeth e<4> on the end of the mandrel so that the two rotate together. The mandrel has a groove e adapted to form in conjunction with one of the discs J the groove and internal rib at the bottom of the vessel, and has also a half groove e<1> cooperating with the remaining half f<1>, formed on the spindle F, in conjunction with the other disc J to form the groove and rib at the mouth of the vessel. The finished tube passes to position 4 where it is ejected from the mandrel by a spring - controlled collar l carried by a rod L engaged by a bracket l<1> on a cam-actuated sliding- rod L<1>. |
