' I This invention relates to sheet insetting I mechanism forrotary multiple web printing machines,

- In asheet insetting machine ofthis kind,

when a sheet from one printing mechanis1n is inset between ,two' sheets from another printing mechanism, it is usualto drive the mechanism printing the'sheet to beinserted at a speed slowerthan (say half of) that of the mechanism for printing the other two sheets. The sheet to be insetis fed by fric- 7 tion rollers or theilike, acting-in conjunction with a cuttingcylinder, towards a collecting cylinderwhich takes; charge of the sheets. At thefmoment that the sheets vare taken in charge by the collecting cylinder, the sheet which is to be insetisfreed from its cutting 7, cylinder and rollers, bymoving'theselatter awayfrom the said cutting cylinder.

Such mechanism," as 'arule, is found 'to work satisfactorily up to a certainspeed, but

I ',if the printing machinebe drivenat'a higher speed, so as,ffor example, to handle 10,000

copies an hour, it is found that the sheet may not be inset inproper position;

'According to the'present invention I pro vide in a machine as set forth above, forthe sheet to beinset," additional feeding means coacting pairs ofsuch, rollers may have their between the usualfeeding device and the collecting cylinder.

In one form of construction such additional feeding means comprises friction rollers,

parts of whose peripheries are stepped back,

the arrangement being such that the sheet'to Ibe inset is disengaged at the moment it is takenin charge by the collecting cylinder.

It is obvious that either one or both of the periphery or peripheries stepped back- In theaccompanying diagrammatic view which illustrates the invention, 1 is a paper web whichis led around a roller 2 and passes between cutting cylinders 3, 4, the cylinder 3 having a knife '5 which registers once during each revolution with a gutter 4:"i'n the cylin der l. 6 is ajcollecting cylinder provided with sheet taking-devices, as

6, and 7 is a cylinder which delivers sheets from the cylinder 6 to folding mechanism (not shown) A second web 8 is led (at half the speed'of theweb 1) around aroller 9 and ispassed between cutting cylinders 10, '11, the'cylinder 10 having aknife 12. which registers once the cylinders 3, 4, is cut by the knife 5, the I portion thus severed passing around the cylinder 6; after the cylinders 3, 4 have' completed another revolution, the web, following the trailing edge of; the severed portion, is cut by the knife 5, the leading edges ofth'is sheetiand the sheet previously severed. meet-1 ingas they pass into the nip of the rollers 4, 6. Simultaneously with the meeting of theleadingedgesof the said sheets, the: lead ing edge of a'sheet-which has beengsevered from the. web 8 bythe knife 12 is fed by the.

tioned sheets,"so-thatthe leadings edges or friction rollers 16, 17, between thefirstmenthe three sheets enter the nip-ofthe cylinders the web 8 ,is released fromthe rollers :16,

What ,I claim is T I 1'; Inasheetinsetting machine, thecombination of cutting cylinders,-a collecting cyle inder, means inaddition;toiand c'ooperating .with the cutting cylinders for feeding th'csheet to be .insetfrom said cuttingcylinders to,s'aid collecting cylinder, and additional means running. at the speed ,of-ithe collecting cylinder forfe'eding the sheet tobe inset 10- cated between the first said means and the collecting cylinder and-havingprovisionfor releasing the sheet.
