Abstract
Abstract Food units consisting of two slices of bread and a filling interleaved with them are prepared by slicing fresh bread and conveying the slices to means in which the desired filling is placed on one slice, whereupon another slice is placed on top of the filling on the first slice. The conveying means includes successive pairs of frames each accomodating one slice of bread, and one frame in each pair of frames is approximately horizontally oriented while the other frame is pivotally connected to the first frame and adapted to be raised ahead of the filling means to permit the filling to be spread over the horizontal slice, leaving adjacent the edges thereof a zone free of filling, whereafter the frames are swung together and pressure is exerted against the marginal zones of the slices to bond them together with the aid of their starch content. The food units are made ready for consumption by being heated for a short time in a conventional toaster.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
187 words
An apparatus for making a food unit consisting of two superimposed slices of bread and a filling interleaved with the slices, said apparatus comprising means for supplying slices by which means the slices of bread are conveyed to means in which a filling is placed on one slice of bread and the other slice of bread is superimposed on the first slice, wherein the conveying means comprises successively advanced pairs of frame having approximately the same dimension as the slices of bread and being adapted each to accommodate one slide of bread, one frame in each pair of such frames being approximately horizontally oriented while the other frame is pivotally connected to the first frame and takes a sufficiently raised position when it moves past the filling means to permit spreading a filling over the horizontal slice of bread while leaving a zone free of filling along the edges of the slice, said frames being adapted to be brought together after they have passed the filling means, and pressing means is provided to exert pressure against the edge zones of the bread slices located between said frames.
Claim 2
Independent Claim
187 words
An apparatus for making a food unit consisting of two superimposed slices of bread and a filling interleaved with the slices, said apparatus comprising means for supplying slices by which means the slices of bread are conveyed to means in which a filling is placed on one slice of bread and the other slice of bread is superimposed on the first slice, wherein the conveying means comprises successively advanced pairs of frame having approximately the same dimension as the slices of bread and being adapted each to accommodate one slide of bread, one frame in each pair of such frames being approximately horizontally oriented while the other frame is pivotally connected to the first frame and takes a sufficiently raised position when it moves past the filling means to permit spreading a filling over the horizontal slice of bread while leaving a zone free of filling along the edges of the slice, said frames being adapted to be brought together after they have passed the filling means, and pressing means is provided to exert pressure against the edge zones of the bread slices located between said frames.
Claim 3
Dependent Claim
49 words
An apparatus as claimed in claim 1, wherein said frames have open central portions and wherein the pressing means is in the form of press plates which are movable into engagement with the slices of bread located between the frames through the respective open central portions of said frames.
Claim 4
Dependent Claim
166 words
An apparatus as claimed in claim 1, wherein the press plate of the horizontal frame rests on an abutment projecting from the inner peripheral edge of said frame, and is at a lower level than the upper boundary plane of said frame, the upper side of said horizontal frame at some distance from the outer periphery thereof is bevelled towards the inner periphery to the level of said press plate in order to form a recess which is defined by the bevel and said press plate, and the press plate of the pivotally mounted frame has in its side facing the recess in the horizontal frame a conforming recess and is insertable in the associated pivotally mounted frame under suitable pressure for bonding the slices of bread while the press plate of the horizontal frame can be moved upwards by suitable means into the space between the frames to serve as an ejecting plate after the press plate of the pivotally mounted frame has been removed.
Claim 5
Dependent Claim
116 words
An apparatus as claimed in claim 3, wherein the press plate of the pivotally mounted frame is adapted to revolve about an axis of rotation extending at right angles to the direction of motion of the frames, and said press plate of the pivotally mounted frame is arcuate on the side facing the frames so that when said press plate is introduced into the pivotally mounted frame the interengagement of the slices of bread is effected by a rolling movement from one end oF said slices to the other end thereof (FIGS. 1 and 4), and the press plate of the horizontal frame is planar and movable at right angles to the plane of the frames.
Claim 6
Independent Claim
37 words
An apparatus as claimed in anyone of claims 1, wherein a flat tubular nozzle is arranged for the supply of the filling, the width of said nozzle being smaller than the width of the slices of bread.
Claim 7
Dependent Claim
73 words
An apparatus as claimed in claim 5, in which the filling is butter or like substance and a further foodstuff, such as jam, wherein the further foodstuff is suppliable through said nozzle while a second flat tubular nozzle is provided for the supply of the butter etc., said second nozzle coaxially surrounding the first nozzle and terminating in the same plane as said first nozzle, and means for supplying foodstuff to the nozzles.
Claim 8
Dependent Claim
28 words
An apparatus as claimed in claim 6, wherein means for cutting off the desired length of filling is arranged in front of the mouths of the two nozzles.
