6 Claims.

This invention relates to new and useful improvements in crimping machines generally and particularly seeks to provide a novel machine for crimping the projecting ends of roll wrappers down onto the end faces of the rolls.

It is an object of this invention to provide a novel crimping machine particularly suitable for crimping the ends or the wrappers on large rolls o'f-paper such as newsprint, and in which the newsprint roll is supported on a pair of driven carrier rolls, one of which is fitted with a pair of 'adiustably mounted crimping assemblies.

Another object of this invention is to provide a machine of the character stated in which means are provided for mechanically ejecting the newsprint r011 after the crimping operation hasbeen completed.

Another object of this invention is to provide a machine of the character stated in which one of the carrier rolls is plain and the other slotted so that operative connections may be maintained between the crimping assemblies carried by the slotted roll. and adjusting devices mounted there- Another object of this invention is to provide amachine of the character stated in which the slotted carrier roll is provided with a spaced pair of collars slidably mounted thereon and resiliently connected to a pair of crimper-carrying sleeves, there being a hand-wheel operated, internally positioned, adjusting screw operatively connected to the sliding collars whereby the spacin between the crimper sleeves can be readiiy varied.

A further object of this invention is to provide a machine ofthe character stated which includes means for quickly locking the adjusting devices in any desired position to maintain constant spacing between the crimpers.

A further object of this invention isto provide a machine of the character stated which is simple in desi n, ru ged in construction and economical to manufacture.

With these and other objects in view, the nature of which will be more apparent, the invention will be more fully understood by reference to the drawings, the accompanying detailed description, and the appended claims.

In the drawings,

Fi 1 is a top plan view of a crimping machine constructed in accordance with this invention:

Fig. 2 is a longitudinal vertical section taken along line 2-2 of Fig. 1;

Fig. 3 is a perspective view of the crimping machine showing a completely crimped paper Fig. '7 is a similar transverse section takenalong line l-l of Fig. 6.

Referring to the drawings in detail, the invention as illustrated is embodied in a crimpingmachine adapted to be mounted in .a pit formed in the floor of the paper mill finishing. room such a manner that the upper surfaces of the carrier rolls are substantially co-planar with the iiocr surface. .A supporting girder 5 is disposed transversely of the floor pit and is located adjacent one end thereof, and a similar supporting girder 6 is secured in the pit in spaced parallel relation from the girder5, a distance slightly greater than the length of the carrier rolls. A plain carrier roll is journalled on suitable bearings T, l on the supporting girders and comprises a hollow shell 8 having one end closed by a plug 9 which is provided with an outwardlyprojecting journal portion [0 rotatably supported in one of the bearings 1. The other end of the shell 8 is similarly closed by a plug ll having an outwardly projecting journal portion I2 r0 tatably carried in the other bearing 1 but of a length sufiicient to project beyond the faceoi the bearing so that a driving gear l3 maybe rigidly affixed thereto.

A slotted carrier roll is journalled on suitable bearings l4, l4 carried by'the supporting girders 5 and 6 and includes a hollow shell portion I! having one end closed by a plug 16. The plug is is provided with an outer skirt portion: 11

which together with the central body portion of the plug defines an annular groove which receives the associated end of the shell iii. A plurality of set screws it are used to secure the shell to the end plug IS. The plug l 6 is provided with an outwardl projecting journal portion 19 wh ch is rotatablv carried in one of the bearings i4 and is of sufiicient length that a driving ear 2!! may be rigidly afiixed thereto, The plug (6 and its associated journal is areprovided with a centrally located bore 2!, the inner end of which is enlarged to receive a ball bearing assembly indicated at '22.

by a plug 23 havin a skirt portion 24 for receiv-- ing the associated end of the shell and an outwardly extending journal portion 25 rotatably carried in the other bearing Hi. The plug 23 and journal 25 are also provided with a central bore 26 having its innerend enlarged to receive a ball bearing assembly indicated at 21.

A spider 28 is secured within the shell in the central portion thereof and rotatably supports the central section of an adjusting screw 29 extending the full length of the shell. The adjusting screw 29 is provided with an end portion 36 of reduced diameter which is seated in the ball bearing assembly 22 and is prevented from axial movement to the right by a collar 3| rigidly affixed thereto adjacent the bearing 22.

vided with a relatively lon extension 32 projecting through and beyond the bore 26 of the plug 23.". It is rotatably supported in the hearing assembly 2? and the adjusting screw 29 is prevented from moving axially to the left by a collar 33 rigidly afiixed thereto adjacent the bearing 21. The end portions of the adjusting screw 23 are oppositely threaded as at 34 and 35. A collar 36 is threadably engaged with the threaded shaft portion 34 "and is provided with a pair of oppos'itelyv disposed radially extending arms 3?, 37 each having a length sufficient to project beyond the periphery of the shell [5. The shell i5 is provided with a pair of diametrically opposed slots 38, 38 through whichthe arms 37 extend.

-A collar 39 is slidably mounted on the shell I5. and is provided with a pair of oppositely positioned mounting lugs 45, 49 rigidly afilxed to the arms 3? so that when the threaded collar 35 is moved along the adjusting screw 2 Qthe collar 39 will be similarly moved. A sleeve 45 is also slidably mounted on the shell 11% and is provided with a plurality of lugs t? in alignment with similar lugs 6-3. on the collar 39. Resilient connections are provided between the collar 39 and the sleeve Ql by a plurality of studs 4 which are carried by the lugs 42 and extend through the lugs 43 and carry compression springs 45 interposed between the collar and the sleeve 4! so that the sleeve aiways tends to be forced away from the collar by action of the spr'ngs. The studs 44, of course, prevent relative rotation of the sleeve 4| withrespect to the collar 39.

The opposite face of the sleeve 4| is provided with a flange d5 having a plurality of notches 47 extending spirally inwardly from the periphery thereof to thereby define four blade-like elements which correspond generally to and provide support for individually fastened crimping elements. Crimping elements 68 are secured to the flange 4.6. and are provided with peripheral edge portions extending beyond the periphery of the flange and include flat face portions adapted to contact the projecting shoulders of the wrapper which has been placed around a paper roll to eiiect the crimping thereof against the ends of the paper'roll.

,A similar assembly, including the threaded collar radial arms {:31 and the collar and sleeve elements connected therewith, is provided adjacent the other end of the shell l5, but, of course,

the threads on the collar 35 will have to be reversed in comparison to those above described in order to be properly engageable on the threaded portion 35 ontheadjusting screw.

'In order that the adjusting screw 29 may be readily rotated to vary the spacing between the crimping elements 48 the end face of the journal 25 is provided with a plurality of radially-formed teeth or dogs 49 engageable with similar teeth or dogs 50 formed in the hub portion 5| of a hand-wheel 52 which is keyed as at 53 to the reduced diameter portion 32 of the adjusting screw 29. The extreme end portion of the screw extension 32 is threaded as at 54 and carries a small locking wheel 55 thereon. A flange or cap 56 is aflixed to the end of the threaded portion 54 and prevents the locking wheel 55 from being completely removed from the shaft. However, the locking wheel 55 can be moved along the threaded portion 54 an amount at least sufficient to provide space for the hand-wheel 52 to be slid axially along the extension 32 to disengage its Y I teeth 5i] from the teeth 43 of the journal 25. The other end of the adjusting screw 29 is pro When this has been done the hand-wheel can be rotated to effect rotation of the adjusting screw 23 and thus vary the spacingbetween the crimping elements 48. After the spacinghas been thus adjusted the locking wheel is again rotated on the threaded portion 54 to lock the hand-wheel 52 into immovable engagement with the journal 25. Thus when the hand-wheel and journal have become locked together the shaft 29, the shell l5 and crimping element assembly car? ried thereon will all rotate as a, unit without any relative movement of rotation between the several parts;

Mechanisms are provided for ejecting the crimped roll of paper and include an ejector roller 57 rotatably supported in a yoke-58 which is afiixed to the upper end of a vertically disposed slide 59 movably carried in a sleeve 60. The sleeve 5i? is fastened of the crimping machine in any desired manner, The lower end of the slide 59 is connected to the upper end of an air or hydraulic piston rod 6! carried by an operating air or hydraulic cylin: der 62. The normal position of the ejector roller 5? is as indicated in full lines in Fig. 7 of the drawings, and when a crimped roll is to be ejected from the main carrier rolls the air cylinder 62 is actuated through any suitable control means (not shown) to raise the ejector roll to the dotted line position and thus roll the crimped paper roll away from engagement with the the floor of the finishing room. noted that the slide 59 is preferably a square or rectangular cross section and the sleeve are similarly sectioned to avoid any torsion to the ejector roll or to the crimped paper roll engaged moved from an operative thereby during the time that the ejecting action takesplace.

The main carrier tively driven in the same direction of rotation through the gears l3 and 2!! whichreceive their power from a centrally located driving gear 63 rigidly aifixed to a shaft 54 bearings 35, 65 and which is connected through a clutch 66 to a reduction gear motor drive generally indicated at 61. The clutch 66 is provided with the usual shifting spider 58 which may be to a non-operative posijournalled in suitable ticn through suitable (not shown). 1

It, of course, is to be understood that various details of arrangements and proportions of parts may be modified within the scope of the appended claims.
