Description
3733~3 THIS INVENTIO~ relates to apparatus for slicing bakery products such as breads, cakes, pastries or the llke, and in one aspect to apparatus for the partial slicing of bread sticks to per~it the subsequent application of a spread such as garlic butter or the like.
~ arious types of equipment are known for the slicing of bakery products. One such kncwn type of appar-atus includes a plurality of rotating knives which move into and across the product to slice the product such as a loaf o~ bread into a plurality of bread slices. In an alternative arrangementl equipme~t employing reciprocating blades is used to cut the bread loaf into slices. The above known arrangements however suffer a number of disadvantages. In particular, the known equipment tends to be relatively unsafe in use, and Curthermore is not suitable for partial slicing of bread products.
The present invention aims to overcome or at least alleviate some ot the above disadvantages by providing apparatus which is suitable for the slicing of bakery products in a safe relia~le and efficient manner. The apparatus o~ the present invention is particuiarly suitable for partial slicing of bread pxoducts so as to permit the subsequent application of a spread such as garlic buttex.
Other objects and ad~-antages of the ir.vention will become app2rent from the followin~ description.
With the above and other objects in view, this invention resides broadly in apparatus for slicing a bakery product including slicing means, conveying meAns for `` -!
~L;23~38 supporting said product and conveying said product past said slicing means so that said slicing means at least partially severs said product, and engagement means opposite said conveying means and movable in substantial synchronism therewith, said engagement means being arransed to co-operate with said conveying means to at least partially compress saia product therebetween and maintain said product in a compressed or partially compressed attitude whilst said product is at least partially severed by said slicing means.
In order that the invention may be more readily understood and put into practical effect, reference will now be made to the accompanying drawings which illustrate a preferred embodiment of the invention and wherein:-Fig. 1 is a partly cut away elevational view of slicing app~ratus according to the present invention;
Fig. 2 is a plan view showing the slicing head of the apparatus; and Fig. 3 is a sectional view along line A-A of Fig. 2 showing details of the slicing head.
Referring to the drawings, there is illustrated slicing apparatus 10 according to the present invention which is suitable for slicing bakery products and in particular 25 for partially slicir.g bread sticks, As shown, the apparatus 10 includes a main elongated frame 11 which is arranged substan~ially horizontally in use and which supports a feed-in conveyor assembly 1~ including a pair of end rollers ~3~33~3 13 and an endless conveyor belt 14 which extends therebetween and a slicing head 15 disposed at one end thereof. Prefer-ably, a fixed horizontal slider plate 16 is disposed beneath ~373~
the surface of the upper run of the belt 14 so that bread sticks 17 may be placed on the belt 14 and suppoxt:ed in their movement towards the slicing head lS.
. The slicing head 15 includes a sub frame 18 pivotally supported at 19 by a pair of supports 20 at one end of the main frame 1~. As shown, l:he sub fxame 18 is disposed at an inclined attitude relati.ve to the main frame 11 and is adjustably supported in that attitude by a pair of stays 21 which extend fxom opposite sides o the sub frame 18 to the main rame 11~ ~ pair o~ rollers 22 are supported rotatably at respectsl~e opposi.te ~nds o~ t:h~
sub frame 18 in respective bearings and each ro].lex 22 is provided with a plurality of spaced annular yxooves 23 so that respective endless belts 24 may he supported between the respective rollers 22. The belts 24 pxefe.rahly axe formed of plastics material and are of circular cxoss sectional form. An idler roller 25 is supported on ~he sub frame 18 intermediate the end rollers 22 and positioned so that the leading portions 26 of tha belts 2~ ax~ inclined downwardly and rearwardly for a purpose hereundex describe~.
The slicing head 15 also includes a cutter assembly 27 which is supported on the main fxame 11 and located intermediate the end rollers 22 of the conveyor assembly 12 and adjacent the idler roller 25 but xearwardly thereof. Preferably the cutter assembly 27 includes a shaft ~8 supported at one end in a bearing 29 support~d by a standard 30 extending upwardly from the main frame 11~
The shaft 28 extends through apertures 31 in opposite.sides ~3~;~3~3 of the sub frame 18 and is coupled at i-ts opposite end to a drive motor 32. The shaft 28 carries a pluralit~ of spaced coaxial cutting discs 33 which are arranged between respective belts 24 and extend therebelow as more clearly illustrated in Figs. 2 and 3. Preferably the cutter discs 33 are provided with a serrated outer cutting edge to improve the efficiency of slicing.
The drive motor 32 is arxanged to drive the shaft 28 and cutting discs 33 in an ant.i-clockwise directi.on in the drawings of Fiys~ 1 and 3 and the belts ~4 and conveyor belt 14 are driven so that t:he upper :rurl of the conveyor belt 14 and the lower run of the belts ~ move in the same direction and at substantially the same speed. .
Preferably one of the conveyor be~t end rollers 1~ and one of the rollers 22 which supports the belts 2~ are driven by the drive motor 32 via respective gear xeduction transmissions 34.
In use a plurality of bread.st.icks 17 are placed one at a time at spaced apart positions on the movi.ng conveyor belt 14 so as to extend transversel~ thereof.
The belt 14 carries the bread sticks 17 towards tlle slicinc3 head 15 so that the upper portions of the respecti.ve ~xead sticks 17 become engaged by the inclined portions 26 of the belts 24. The respective belts ~4 and 14 then serve to grip the bread sticks 17 and cause progressive compression thereof as the sticks are moved rearwardly by the belts 24 and 14. When the cutting assembly 27 is reached, the bread sticks 17 have been compressed to approximately .

~l~3~733~
one-third to one-half of their normal height. The belts 24 and 14 then continue to move the compressed bread sticks 17 past the cutting discs 33 which penet.rate the upper surfaces of the bread sticks 17 to form a plurality of slits therein. A clean cut is achieved because the respective upper belks 24 on either side o each cutt:er disc 33 support the bread stick du.ring the cuttinc3 pxocess.
The slit bread sticks 17 are then fed rearward~y b~ both the belts 24 and 14 to be discharged from the apparatus.

many different types of bakery prod~lcts and if say a larger product is required to be sl:i.t, t}le su~ fxame 18 of the slicing head 15 may be pi~oted upwardly and supported at a greater angle relative t:o the main ~rame so as to permit the product to pass t]:lrou~h.~he appara~s 10. As is described above~ the apparatus is particularly suited for partial slicing of a baker~t product and fox this purpose, the cutting discs 3~ are arranged so that the cutting edges thereof are spaced above the conveyor belt 14.
