Thisl inventionrelates toV paper roll heading machines u'sedj` for applying adhesive disks of pape-r or the 'like to' the'ends of a wrapped roll of newsprint Aoifother paper.

More particularly, thev invention consists inthe provision' of an'improved rollheading machine in which 'the' head'erf disks-employed' for vpressing the paper disks-against the ends of the Wrapped roll `of paper are--carriedbypistons' working in cylindersniounted"=oii ya's'uitable` base frame; one of said-cylinders preferablyfbeing stationary and the other cylinder being movable to diierent positions of v'adjiistinen't'to Suit'the leng'th'ofthe paper roll being headed.`

Another'feature of the invention consists in theY provision of novelmeans for clamping" the movable cylinder to the base frame to holdsaid cylinder stationary on the frame during the roll heading operation.

A-further feature of the inventionI consistsin providing the base frame of the improvedroll heading maohine'with rollers over'which movable cylinder travels during adjustmentthereof; said rollers alsoserving to' support the paper 'roll during the roll ll'ieadin'gf operation'.

Other features and advantagesl of fthe invention will be more? readily understoodfromthe follovvf` ing detailed description` taken in'connectionwith the accompanying drawings,y

This frame is equipped with transversely extending rolls 9 spaced along-the bottom plate 6' in e1eVa-tedr'el`ation thereto. Each roll is journalled in' support ing b-rackets I rising fromlbottom-plate Ii in spaced reiation to the side channels 1.

A stationary cylinder II is located at oneend of framed-and is supported thereon byaiiied supportingbracket -orstandard-' I2. Cylinder I I contains a piston (notshown') lwhich operatesfa hollow header disk I3 fixed to piston rod I 4 by connecting means I which permits the disk to oscillate slightly in all directions relating to said piston rod. Disk I3 is electrically heated by a suitable electric heating coil or resistance contained therein. This heating coil or resistance 2 is notlshown'fsinc'eit may bei of` anysuitable type and-'may' bei connected in any suitableelectrical circuit arrangement;

Disk I3 is opposed to and :zo-operates` with a similar' header disk IIIcarried by lpi'sto'nrod- I'I o fa piston (not shown); working inl a'V second travelling cylinder' I 8' carried by" a; supporting bracket I9 arranged to travel on ther rolls Bin the lengthwise direction ofthebase..I

Asshowntoadvantagein Figszand 4, bracket Ilifincludes a hat-roller engaging base or bearing portion'` 2E!I provided with marginal gripping flanges 2| disposed beneath the top flanges 22-of channel members 1.

A pair"of gripping'jaws-,Mare*arranged-'at oppositsidesoffbracket" I wand-arev 'pivote'd thereto as' indicated at"25- The lowerends 261offjaws -24' are disposed `above thectop'flangesf22of channel members 'Iz The upper' 'ends of t jaw 25- areprovided with openings 2'1- for'Y the "passage,-A ofl a jawvk operating screw 28 whichialso passesthrough/a-n opening 29inthe upper portion iof i bracket I 9:

When Ithe/fjaws. 24'are` positioned as'shown in Fig. -lr-theylieabove andfclea'r of the top flanges 22 of the framechanneVI.` Inthis positionof jaws 24- the flat base or bearing i portion 20 'of bracket" I Brestson andis sup-ported bytheunderlyingfro'llers. In this position'of jaws 24and bracket'l 9 the' assembly comprising disk I5 cylinder' I8^and=bracket" I9 is -free toi travel over the rollers B't any. desired position-of adjustment along 'the1base I5-to suit the length ofthe lpaper roll'to b'eh'eaded: A iter'thel cylinder I8- hasl thus been shifted to the desiredposition'onifram-ev 1; it' is secured in'adjusted positior'iby operating the'fscrew shaft Zftofswing jaws-24 from the posi-l nbnfshown'inf-Fig;4to' Fig: 3. During this opera-` tion of jaws 24 the lower ends 26 are brought into engagement with the top flanges 22 of side channel 'I to exert a lifting action on the bracket I9 which results in raising said bracket to a position in which the top flanges 22 of side channel 'I are firmly clamped between the gripping flanges 2| of bracket I9 and the lower end portions 26 of jaws 24. Bracket I9 is thus raised clear of its supporting rolls 9 and firmly clamped to the base frame I to hold the cylinder I8 stationary during the roll heading operation.

The machine described herein is used in the customary manner for roll heading operations. The paper roll to be headed is placed Aon the supporting rolls 9 of frame 'I so that it lies between the disks I3 and I6.

The paper roll is placed on the supporting rolls 9 with disks I3 and I6 retracted to the dotted line position shown in Fig. 1. If the distance between cylinders I I and I8 is too great for effective hea-ding of the roll, the cylinder I8 is movedv the required distance in the direction of cylinder I I, and is then clamped in place by the clamping jaws 24. The heading operation is then proceeded with by 4 roll heading unit against movement relatively to said frame.

3. In a roll heading machine, a base frame including side members provided with inwardly directed flanges at their upper edges, transversely extending rollers journalled in said frame between said side members, a roll heading unit movable longitudinally of Vsaid frame, said unit comprising a cylinder, a header disk carried by a piston working in said cylinder, a cylinder-supporting velement including a base portion normally supported by said rollers for free travelling movement longitudinally of said frame, said base portion including marginal portions underlying said flanges .and means for raising the base portion of the roll heading 'unit clear of said rollers and into pressure contact with the lower surfaces of said applying adhesive header disk of paper to the ends of the paper roll and then operating the pistons of cylinders I I and I8 to force the heated header disks I3 and IB of the machine against the said paper disk to complete the roll heading operation.

The rolls 9, on which the paper roll is supported, also enable the paper roll to be centred between -dlsks I3 and I5 by the centering action of the roll heading units.

Having thus described thenature of my invention and a preferred embodiment, it will be understood that various modifications may be resorted to within the scope and spirit of the appended claims.
