The foil is fed from a reel 25 mounted above .the nia- 25- chine, the'reel being of a width equal to the length -of ',the foil strip. The foil is feddownwardly by a pair. of rollers26 adaptedjto emboss a design on -..the sameand from these rollers it passes to another'p'air of rollers-'27. whichpull the foil, from the embossing rollers.

'Theiweb of foil next passesinto a cutting mechanisrnfcomp'risinga rotary knife 28 and a soft v.co. operating roller 29 against which the knife acts, in which a strip ofIfoil of the required width is severed, and at the instant of cuttingthe lead- 7 ing edge of the foil is seized by a rotary suction device 30' which carries the foil downwards and deposits itfiat upon the carton blank, the suction the instant the foil comes to rest on the blank. V v V I After the foil has been applied to the blank, the intermittent conveyor moves on another stage andcomes torest with'apair of blanks in line with'the' twosets of vane openin'gsof the cigarette feed and two batches of cigarettes are deposited upon two successive blanks in the mannerpreviously described, after which the conveyor moves on a'stage at a time.

A gripping device 31, Fig.v 6,'operated by a cam (notshown) is arranged to hold thefoil in posi- -ltionon the blank by pressing the latter against a projection 31?. extending. downwardly from the plate portion of the member '6 which overlies the'bed .7 until the. first batch of I cigarettes has been deposited thereon. This may be conveni ently effected by periodically raisingthe'gripping.

, During the movement which followsflthe cigarette feeding, the cover members 32 and 33 are folded over by folding devicesjhereinafter described, and the folded blank showninjFig, 14'

is removed by a reciprocating-claw 34 into, the path of a. conveyor 35, this conveyor being of the which travels at right anglesjo thepath of the intermittent conveyor ,8.

v In some instances it is desirable tore inforce the hinge member .of the double pocket carton, and this 'ispreferably carried out by feeding a l) strip of material36g of approximately the same size as the hinge member to the flatcarton blank. Mechanism for performing this operation is shown in Figs. 1 and 2 and. comprises a magazine strips are carrieddown the guide in succession rigid'therewith, and operated by the cam mech- .anism 46 and .they are subsequently pressed heavily'on to the blank at the next stationary presser bar (not shown)-- 1 In order to-bend these spring fingers over they r are first bent upwards bya cam operatedpress'er 47 (Fig. 7), after whichtheyare turned down o nto the faceof the blank by a folder 48 to the Thefingers are kept in contact with the blank whilst-the strip of foil is app lied to the blank.
