1. In' a lcup making machinawherein a paper cup' "is'held in aconical `holder having la conical anvilinsert having 'an'u'pstanding annular top endz" a vertically 'movable bracket having a head with a spindlebearirg; a spindle''longitudinally movable in' said" head; a cover' for the top'end ofthe' cup'and" fitting loverthe top edge 'of the anvil insert and having"a stepped recess 'of two l diameter's`,'"'said 'head' "being" mounted" on 'said' spindle; a segmental beader having an annular iange and being located in part in the recess of the larger diameter in said cover and having an annular groove; a spring in said groove for holding the segments of the header together; a nose on said spindle and projecting through the center of said segmental header and having a wedging engagement with the segments; a header cup clamp on the projecting end o said nose and supporting said segments, said clamp having radial grooves and said segments having pins guided in said grooves; a spring continuously urging said spindle in one direction; and means to limit the spindle movement in said direction, said anvil having a bead-forming groove into which the flange on the segmental header presses the cup material.

2. n a cup making machine wherein a paper cup is held in a conical holder having a conical anvil insert having an upstanding annular top end: a vertically movable bracket having a head with a spindle bearing; a spindle longitudinally movable'in said head; a cover for the top end of the cup and fitting over the top edge of the anvil insert and having a stepped recess of two diameters, said head being mounted on said spindle; a segmental header having an annular flange and being located in part in the recess of the larger diameter in said cover and having an annular groove; a spring in said groove for holding the segments of the header together; a nose on said spindle and projecting through the center of said segmental header and having a wedging engagement with the segments; a header cup clamp on the projecting end of said nose and supporting said segments, said clamp having radial grooves and said segments having pins guided in said grooves; a spring continuously urging said spindle in one direction; and means to limit the spindle movement in said direction, said anvil having a head-forming groove into which the ange on the segmental beader presses the cup material, and a spring continuously urging said cover in one direction.

3. In a cup making machine wherein a paper cup is carried in a conical holder having a conical anvil provided with an upstanding annular top end and a head-forming groove: a vertically movable bracket having a head with a spindle bearing; a spindle vertically movable in said head; yieldahle means continuously tending to move said spindle downwardly; a cover for the top end of the cup and iitting over the top edge of the anvil and having a recess, said cover being slidably mounted on said spindle; means continuously tending to move said cover downwardly, a nose on said spindle Awithin said cover to limit the downward movement of said cover; a segmental header having an annular flange and being located in part in said cover and engaging said nose; a cup clamp carried by said nose and having radial grooves one for each header segment; guide elements on said segments for cooperation with said radial grooves; yieldahle means continuously tending to hold said segments together in retracted position; and means operating to rst bring said cup clamp and said cover into operating position and thereafter eiect movement of said nose to expand said segments and cause said annular flange to press the cup material into said head-forming groove.

4. In a cup making machine wherein a paper cup is carried in a conical holder having a conical anvil provided with an upstanding annular top end and a bead-forming groove: a vertically movable bracket having a head with a spindle hearing; a spindle vertically movable in said head; yieldahle means continuously tending to move said spindle downwardly; a cover for the top end of the cup and tting over the top edge of the anvil and having a recess, said cover being slidahly mounted on said spindle; means continuously tending to move said cover downwardly, a nose on said spindle Within -said cover to limit the downward movement of said cover; a segmental beader having an annular flange and being located in part in said cover and engaging said nose; a cup clamp carried by said nose and having radial grooves one for each header segment; guide elements on said segments for cooperation with said radial grooves; yieldahle means continuously tending to hold said segments together in retracted position; and means operating to first bring said cup clamp and said cover into operating position and thereafter effect movement of said nose to expand said segments and cause said annular ange to press a head into said head-forming groove, said last named means including a cam shaft, a cam on the same, an operating shaft with a cam roller to engage said cam, a shaft guide for said shaft, said bracket being mounted on said shaft.

5. In a cup making machine wherein a paper cup is carried in a conical holder having a conical anvil provided with an upstanding annular top end and a lhead-forming groove: a vertically movable bracket having a head with a spindle bearing; a spindle vertically movable in said head; yieldahle means continuously tending to move said spindle downwardly; a cover for the top end of the cup and fitting over the top edge of the anvil and having a recess, said cover being slidahly mounted on said spindle; means continuously tending to move said cover downwardly, a nose on said spindle within said cover to limit the downward movement of said cover; a segmental header having an annular flange and being located in part in said cover and engaging said nose; a cup clamp carried by said nose and having radial grooves one for each header Isegment; guide elements on said segments for cooperation with said radial grooves; yieldahle means continuously tending to hold said segments together in retracted position; and means operating to rst bring said cup clamp and said cover into operating position and thereafter effect movement of said nose to expand said segments and cause said annular ange to press a bead into said bead-forming groove, said last named means including a cam shaft, a cam on the same, an operating shaft with a cam roller to engage said cam, a shaft guide for said shaft, said bracket being mounted on said shaft, said shaft guide having a pilot pin guide, and a pilot pin carried by said bracket and operable in said pilot pin guide.
