This invention is forimprovements in or relaiting'to wrapping machines for caramels or the like ofthe type comprising a movable carrier (such .as' :a wheel, an endless chain, an oscillat'able. arm or the like) v.pro vided with one or more receiving pockets and movable intermittently to bring said pocket (or each pocket inturn as the case may be)' into a position opposite to a reciprocating pusher which :operates intermittently to feed the caramels or other articlesyone at a time,

pocket so that as the pusher advances the caramel the wrapper is carried with it and 1 partially folded about the caramel, the completion of the folding operation :being effected, in the case of -a machine of the carrier wheel type, during the continued step-bysteprotation of the wheel.

The present invention is concerned with a wrapping machine of the above type in which carame'ls.

7 An example of the invention will now be describedwith reference to the accompanying'drawings in which Figure 1 is a plan view showing the general arrangement of the machine.

Figure 2 is a front elevation of part of'the machine, showing in particular the caramel feeding mechanisn'i.

Figure 4: is a plan of the rota transfer membefi H s v g peripheral caramel receiving pockets each constituted-by a stationary jaw 11 (Figure 3) and a movable jaw 12; In the present examplethere are six pockets arranged at equally spacedintervals, and the carrier wheel is so driven as to movethrough one'sixth of a revo- "The stock which-is'in the form of a continuous bar 13 "(Figure 2) is fed along a horizontal guidewayjlt by means of feed rollers 15,16-located onefabove the other,

and thence over abridge piece17 and between rollers 18, 19 which-are arranged side by side to feed the forward end of the bar downwardly through a vertical guide tube Thefeed rollers 15,16, 18 and 19 are all mounted with theiraxes at right-angles to that of the carrier wheel 10. Below the guide member 20 the bar is severed into separate caramelsfby a knife 21 which is operated to rotate continuously in a horizontal plane. The position to which the leading end of the stock bar is fed,-and at'which the knife operates,

hashereinbefore been'referred to as the cutting-station, which as will be seen from "Figure 1) is oif-set laterally from the plane of rotation of the carrier wheel 10. In order to convey the caramels one at a time from the cutting station up to the carrier wheel the fol lowing mechanism is provided.

Referring to F1gures3 and IIIGQh ZLIlISmCOmPIISGS a ring 22 carried on a sleeve 23 WlllGlI 1s mounted for rotation on a 4, the transfer fixedvertic'al pillar 24. The ring 22 has formed in it four channels 25 at equal inter- .valsapart, and 'the'ring has imparted to it a step eby-sjtep rotational movement such that at each step the ring is rotated through quar-v ter of a revolution. The ringis driven through a Geneva stop mechanism comprising" the usualstar-wheel 26 and driving pin 27, a such mechanism ensuring that between each actuation ofthe ring the latter is held securely against backward or forward movement.

The ring 22 is so positioned that during each of the intervals at which it is at rest, one of the channels 25 will be in .a position immediately below the guide member 20, while an adjacent channel will be in a position (herein referred to as the wheel charging station) opposite to the carrier wheel 10. Thus the arrangement is such that one quadrant of the circular path round which the channels 25 are moved, forms the quadrant path through which each caramel'is conveyed fromthe cutting station to the wheel-charging station. Theleading end of the bar of stock 13 is fed into one of the channels25 and while in this position the knife 21 operates to sever the end portion ofthe ,bar thus forming an individual caramel. Each of the channels 25 forms a caramel holder to engage the base andoppositeend walls of a caramel. During the movement of each channel 25 between the cutting station and the wheel-charging station, the sides of the channel are enclosed, on the outside of the ring by an arcuate guide 28, and on the inside of the ring by a circular head 59 carried on the fixed spindle 24:2Lb011t the axis of which the ring rotates. The guides 28, 59 ensure that when the cutting of the bar of stock is efl'ected the leading end (which will form the caramel) is enclosed on all four sidesby the guides 28, 59 in conjunction with the end walls of the channel 25. This feature of the apparatus is important as the complete enclosure of the stock end during cutting prevents that distortion of the caramel which has v pusher is mounted on an arm 30 the outer end of which is. hinged to a short link 31 attached to a sleeve 32 which in turnis mounted on a bracket 33 in such manner that the sleeve can turn about a vertical axis 34. The pusher is operated by a two- part lever 35, 36 pivotally' mounted for. rocking movement about a vertical axis 37. The part 36 of the lever'is pivotally connected at itsouter end (by a spindle38) to a-point intermediate in the length of the pusher arm 30 and the part 35 of the lever carries cam followers 39 cooperating with a cam (not shown) which imparts a to-and-fro movement to the lever and consequently a similar movement to the pusher arm. The various parts associated with the pusher are so arranged that the movement of the latter is confined substantially toa straight line path. The operative end of the pusher 29 is located within a groove 40 which extends diametrically across the circular head59 and is opposite to the position occupied by each caramel-holder channel 25 when at the wheel-charging stapusher 29 duringits advance...

tion. ."During each forward stroke ofthe pusher, the leading-end thereof engages a caramel at the charging station and "forces it out of the channel 25;thro'ughi.a mouthpiece 41*and into one of the carrier wheel pockets. I

Rollers are arrangedv tofeedfla continuous wrapper strip 51' into a position between the periphery of the carrier'wheel 10 and the mouth of theguide 41. In this position the leading'endof the wrapper strip is heldby two pairs of grippers 52, 53and while so hold is severed from the remainder'of the strip by a knife 54, thus forming an inclividual wrapper for one caramel. The grippers'52, 53 are operatedto open and close at the required times and to travel with the The machine operates in the followingsequence. In the positions of the parts shown in'Figure lithe feed rollers 15l9 have'been strip 51 has been fed to the front of the carrier wheel, a wrapper has been severed by the knife 54, and one of the pockets in the carrier wheel 10 is situated in the path of the pusher 29, the carrier wheel being stationary. The pusher is now advanced to force the caramel out of the channel 25 into the wheel pocket, the wrapper being wrapped, in knownmanner about the top and bottom surfaces of the caramel. During the continued step-by-step advance of the carrier wheel the wrapper is folded about the fourth side of the caramel so as to form an open ended tube, the ends of which areclosed by twisters after the operation of which the wrapped caramel is discharged from the machine. WVhile one of the caramel holders 25 is at the Wheel charging station and while the pusher is operating, another holder is positionedat the cutting station and is receiving another caramel.
