Abstract: A method for producing ceramic green sheets allows the foreign substances on the surface of a carrier film to be reliably removed, prevents fluctuation of the path line when a carrier film is transferred by a foreign substance removal device, and enables a ceramic green sheet having a low local variation in thickness to be achieved. In this method for ceramic green sheets, a carrier film is transferred, the transfer direction of the carrier film is changed by a support roll, and the foreign substances on the carrier film surface are removed by an adhesive roll as a foreign substance removal device at the area where the carrier film is in contact with the peripheral surface of the support roll. Then ceramic slurry is applied on the carrier film using a ceramic slurry applying unit, and thereby a ceramic green sheet is formed.

Abstract: Material, for example food material, is extruded through an extrusion die and cut into individual portions by a cutter blade which reciprocates across the die. A hot air blower device directs hot air against the cutter blade to prevent the food material, e.g., pretzel dough, from adhering to or accumulating on the cutter blade, thereby reducing machine down time caused by the need to periodically stop and clean the cutter blade. The hot air blower device receives cool air which is passed through the hot air tools and expelled as hot air by a fan-shaped nozzle disposed opposite the cutter blade.

Abstract: A calendar for the production of packing sheets has a heated cylinder of large diameter on which a packing sheet is progressively built-up of layers of rubber-fiber mixture during many revolutions and the cylinder and an unheated counter pressure cylinder of smaller diameter mounted in slidable bearings for rotation and for movement toward and away from the heated cylinder. As the packing sheet is progressively built-up on the heated cylinder, its thickness is continuously measured by feeler rollers pressed lightly against the surface of the packing sheet and associated inductive sensors.

When the value of the thickness indicating signal equals the sum of the zero value and the desired value, the calender is stopped.

Abstract: A vertically disposed nozzle continuously extrudes a descending column or bar of semi-frozen confection which passes through a ring gear. A cutoff wire is anchored to the ring gear and to a second, laterally adjacent ring gear. Slip rings adjacent the ring gears electrically energize and heat the cutoff wire. Both gears are driven in the same direction, and the anchor points are located to maintain uniform interspacing and thus keep the cutoff wire linear to transversely slice the moving product bar. The gears and cutoff wire are adjustably mounted to be unitarily tilted from the horizontal so that the product bar is repetitively severed along parallel lines to produce slices each having uniform thickness, with the severance lines perpendicular to the side surfaces of the product bar. A wiper is arranged to clean the cutoff wire after each cutting stroke so that the product will not accumulate and burn onto the cutoff wire.
