Abstract
Abstract Apparatus for automatically making food products in piece form, such as loaves of bread, from dough-like substances, comprises a housing having holding drums (230,232) adapted to be fixed to either end of a flexible sealable bag (12) containing the ingredients. A dough preparation and baking chamber (212) has upper and lower slit openings (220,222). The bag is moved to and fro through the slit openings to perform kneading of the dough, and then baked in the chamber. The variable baking parameters dependent upon the particular ingredients and product are controlled dependent upon instructions read from the bag by a scanner (270). The instructions comprise a bar code (121) which can have a first identification portion to confirm that the bag is suitable for use in the apparatus and a second command portion to instruct the apparatus as to the baking sequence required.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
140 words
Apparatus for automatically making food products in piece form from dough-like substances, comprising a housing containing holding means adapted to be affixed to opposed edges of a flexible bag containing ingredients for the dough-like substance, kneading means for mechanically working the ingredients in the bag and including moving means for creating relative movement between the bag and the kneading means so that the ingredients are kneaded into a dough-like substance, heat treatment means for baking the kneaded dough-like substance, and programmable control means for controlling the sequential operation of the kneading means and heat treatment means, wherein the apparatus further comprises scanning means located adjacent the path of the bag as moved by the moving means for reading machine-readable indicia on a bag and for providing an output coupled to the control means to command operation of the control means.
Claim 2
Dependent Claim
140 words
Apparatus for automatically making food products in piece form from dough-like substances, comprising a housing containing holding means adapted to be affixed to opposed edges of a flexible bag containing ingredients for the dough-like substance, kneading means for mechanically working the ingredients in the bag and including moving means for creating relative movement between the bag and the kneading means so that the ingredients are kneaded into a dough-like substance, heat treatment means for baking the kneaded dough-like substance, and programmable control means for controlling the sequential operation of the kneading means and heat treatment means, wherein the apparatus further comprises scanning means located adjacent the path of the bag as moved by the moving means for reading machine-readable indicia on a bag and for providing an output coupled to the control means to command operation of the control means.
Claim 3
Dependent Claim
58 words
Apparatus according to claim 1, in which the scanning means is adapted to read first indicia to provide identification that the bag is of a type suitable for use in the apparatus and second indicia adjacent the first indicia to provide automatic commands to the apparatus determinative of selected parameters relative to the kneading and heat treatment means.
Claim 4
Dependent Claim
20 words
Apparatus according to claim 2, in which at least one of said indicia comprises a bar code or part thereof.
Claim 5
Dependent Claim
16 words
Apparatus according to claim 2, in which said first indicia comprises a characteristic design or figure.
Claim 6
Dependent Claim
27 words
Apparatus according to claim 2, in which the control means is enabled in response to the first indicia to accept commands in response to the second indicia.
Claim 7
Dependent Claim
168 words
Apparatus according to claim 1, in which the holding means comprise upper and lower cylindrical drums for receiving the opposed edges of the flexible bag, and the kneading means comprise an upper and a lower pair of opposed rolls each adapted to provide a slit opening therebetween through which a bag can pass, and means for opening the upper rolls to permit gases in the bag to escape the opening means comprising cam means at opposed ends of the upper drum rotatable about the axis of rotation of the drum, abutment means on the drum and the cam means for causing the cam means to reciprocate between a first and a second position upon reciprocatory rotational movement of the drum, the cam means having a peripheral cam surface thereon, pivotable lever means engaging on the cam surface to be pivoted thereby and connection means longitudinally movable by the lever means to cause translational movement of one of the pair of upper rolls towards and away from the other.
Claim 8
Dependent Claim
109 words
A machine method of automatically making food products in piece form from dough-like substances, comprising the steps of providing a bag containing ingredients for the dough-like substance, creating relative movement between the bag and kneading means such as to mechanically work the ingredients in the bag to knead the ingredients into a dough-like substance, and baking the dough-like substance, the kneading and baking being controlled by a stored program, wherein the method further comprises an initial step of automatically scanning the bag in its path of movement to read machine-readable indicia on the bag and commanding the stored program to control the kneading and baking steps in dependence thereon.
Claim 9
Dependent Claim
109 words
A machine method of automatically making food products in piece form from dough-like substances, comprising the steps of providing a bag containing ingredients for the dough-like substance, creating relative movement between the bag and kneading means such as to mechanically work the ingredients in the bag to knead the ingredients into a dough-like substance, and baking the dough-like substance, the kneading and baking being controlled by a stored program, wherein the method further comprises an initial step of automatically scanning the bag in its path of movement to read machine-readable indicia on the bag and commanding the stored program to control the kneading and baking steps in dependence thereon.
Claim 10
Dependent Claim
66 words
A method according to claim 7, in which the scanning step comprises scanning a first machine-readable indicia to provide identification of the suitability of the bag for use in the method and scanning a second machine-readable indicia adjacent the first to provide automatic commands for the stored program determinative of selected parameters relative to the kneading snd baking steps appropriate to the ingredients in the bsg.
