MACHINE FOR WINDING PAPER BELTS.

Filed Oct. 51, 1931 Patented July 25 1933 UNI ED S ATES P TENT" i oFFicc OAN nnRm NAnNnKRuIMEtL, or" BLoEMENnAAnN TnERLAnns a MAGHINEIOR WINDING PAPER BELTS.

Application filed October 31; 1931, Serial No. 572,307, and inGermany J'u ne 6, 19S 0.

The invention relates to a machine for winding paper belt, in which the belt arrives on a Winding roll, which rests on a driving drum, from which it receives its motion, the roll moving automatically from its initial position as it is wound with paper. The invention has for its object to facilitate the,

quick replacement of the winding rolls when one roll has been wound to the full diameter and the belt has to be transferred to" an empty roll,which is brought into the machine for that purpose, whereas the finished roll of paper isremoved from the machine.

1 The accompanying drawing exemplifies the subject of the invention in an embodiment. p

A driving drum 1 is providedto drive'the winding rolls 2 and 3 which touch the drum 1 at its periphery, sothat the rolls are rotated the action of friction. The empty winding roll 3 rests at the commencementof the winding operation with its trunnions 5 at'both,

ends in bearings 6, whichare open at their This mechanism ensures that bothframes move in unisonv and that the winding roll 40 moves always parallelto itself. This roll is friction. The winding roll 3 is in-its initial position so far removed with its axis from corresponding to the direction of movement of the paper 12 (arrow 21) that theroll moves against the pull exerted by the weights -9 in the direction 21 as its diameter increases of the roll is thus gradually 'removed'from with a uniform peripheral'velocitythrough:

upper halves and are each supportedby a one side by the action ofthe weights 9, which "e Wmdmg r011 pressed by the pull of the weight against the driving drum 1 and driven by the action of the axis of the drivingdrum 1 in adirect-ion due to the paper which is wound up; the axis bearings are so formed that they take up th trunnions 5 of the winding roll 3, the levers 1? beingto thisjendinclined againstthe direction of movement of the winding roll 3; The action ofthe mechanism described is the followingz' j 7 i 6 The paper belt 12 arrives'on the empty winding roll 3 in the directioniof the arrow 21and isfwound on this roll. The diameter of the roll 3 now increasesdue to the succesisive paper layers and moves accordingly 6 from ts initial position, the halfbearings 6 moving at the-same time in the direction of the arrow 21, sothat the trunnions 5 of the roll 3 move finally into the open bearings 16 ofthe levers 15.- These levers nowstart to turn in the direction of the arrowf23 when thediameter ofzthe roll further increases, by which action the trunnions 5 of the roll are lifted from the open bearings 6, which are in this way entirely freed. a v 'Having thus beenliberated the bearings 6 automatically slide back under: the action a of the weights 9 to their initial position,- in which they are" ready .to receive another so The winding of the paper onthe' roll now carried by the levers is continued, till this roll has obtained the desired-maximum diam-- eter, so that it finds itself forinst'anoe' atthe; position'indlcated at 2,' the-trunnionslthen'be ing situated at 4. At this moment-the ,ad:

vancing paper belt is separated from-the i finished roll andiled onto the empty winding.

roll 3", -which liesin readiness,- so that the winding operation may be continued without interruption. The finished roll may now be taken from the bearings 16 of the levers 15 a which have previously been immobilized abolt," for whichremoval a crane may be used. The levers 15 are then returned to "their initial position after removal ofthe bolt, in which they are again ready to talre'up the trunnionsb of the freshroll and the action may now be repeated.

It is clear that the invention is not limited to the embodiment shown, but that modificav tions in theconstruction are possible','such as thereplacement of the frames by another set of levers moving in vertical planes. p
