Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
168 words
In a sandwich-making assembly system, apparatus for slicing a prismatic bar of thermoplastic comestible which comprises means for tempering a prismatic bar to a pre-determined temperature ranging from below 0*F to 20*F and above that temperature whereat the bar may be sliced without shattering but below that temperature at which the bar will soften or curl incident to slicing; means for transversely slicing said bar across its cross-section; means for receiving the slice thus formed and transferring it to a depositing station operative to move the slice transverse to the bar''s axis; means for positioning the transferred bar slice to a station from which it may be dropped onto a bread slice; means to advance the bread slice and superposed sealing slice to a succeeding operating station; and, means controlling the atmospheric temperature and moisture in the zone surrounding the foregoing bar slicing, transferring and depositing means so as to maintain a low relative humidity in said zone and assure that the parts thereof are substantially frost free.
Claim 2
Dependent Claim
168 words

Claim 3
Dependent Claim
28 words
Apparatus according to claim 1 wherein said transfer means are operative to move the slice transverse to the bar axis upon deposit of the slice on said means.
Claim 4
Dependent Claim
19 words
Apparatus according to claim 1 wherein said zone is formed by the action of a subliming refrigerated gas therein.
Claim 5
Dependent Claim
11 words
The apparatus of claim 3 wherein said gas is carbon dioxide.
Claim 6
Dependent Claim
60 words
In a system according to claim 1, means for feeding pre-sliced bread onto conveyor means, conveyor means for receiving the individual bread slices and conveying them to the station from which the bar slice is dropped onto the bread slice, and means synchronizing said bar slicing, transferring and depositing means with operation of the bread slice feeding and conveying means.
Claim 7
Dependent Claim
64 words
In a system according to claim 5, means for applying to the edge of a bread slice an edible sealing composition prior to depositing of the bar slice on said bread slice, means for depositing a bread slice on top of the superposed bar slice and lower bread slice, and means for sealing the superposed bread slices through the intermediation of said sealing composition.
