Abstract: A process for automatically and continuously manufacturing lasagne by forming a continuous sheet of pasta which contains first through fifth longitudinal surface area rows; passing the pasta under a first sauce dispenser which dispenses different kinds of sauces onto the middle three surface area rows of the sheet of pasta; folding the respective outer surface area rows over the respective next inner surface area rows; dispensing additional sauce over an exposed surface of one of the outer folded surface area rows; and further folding the sheet of pasta so that the first through fifth surface area rows are vertically aligned. Subsequently, the sheet of pasta is cut into predetermined sizes, and each predetermined size is placed into its own corresponding food tray. Thereafter, each predetermined size of lasagne is frozen. This process allows lasagne to be efficiently and quickly produced at a relatively low cost.

Abstract: An apparatus is disclosed for continuous distribution of a latex or urethane foam composition on a movable substrate to produce a foamed sheet material such as a foam backed carpet. The distribution apparatus comprises a generally cylindrically shaped rotatable member and at least two attached distribution means which may take the form of either modified doctor rolls or modified doctor blades. The distribution surface of each of these distribution means may differ and may be either smooth or patterned with a variety of grooves or serrations thereby providing means for producing foamed sheet materials with surfaces which are either planar or patterned with ridges and valleys. Means are also provided to readily change the thickness of the distributed foam and for oscillating the distribution apparatus to produce a surface with wavy as opposed to linear patterns of ridges and valleys. All of these operations may be accomplished without interrupting the continuous process.

Abstract: A food preparation machine primarily designed for the production of the Italian potato based delicacy gnocchi and characterized by an inclined flouring ramp, a motor driven roller located under the lower end of the ramp, a deflection plate located proximate the roller, and a dough extruder for depositing dough plugs near the top of the ramp so that they roll and slide down the ramp into abutment with the deflection plate and the roller. As the roller is rotated the dough plugs are squeezed through a gap between the roller and the lower edge of the deflection plate to take on the characteristic form of gnocchi. A flouring mechanism is provided to flour the parts of the machine that come into contact with the dough, including the ramp and a rotating knife blade which cuts the extruded dough into the plugs. The roller is threaded from both ends with opposing threads so that the plugs are urged towards the center of the roller as it is rotated.
