Patent number: 5411390Abstract: A machine for producing configurated products including a rotary die roll having die cavities therein and a pair of feed rollers for feeding viscous product into the die cavities. The feed rollers may be easily moved away from the die roll and the die roll may be rolled out of the machine to allow replacement thereof. Relief members extend from a backing knife between adjacent die cavities of each row as the die roll rotates. These pressure relief pads reduce the amount of product contained in the pressure chamber and thereby reduce the amount of working of the material as it is forced into the die cavities. The machine includes a front shearing knife having removable and replaceable shearing inserts. The feed rolls of the machine include longitudinally extending tapered recesses with opposed recesses of the respective feed rolls being staggered at the inlet of the pressure chamber to cause particulates within the feed product to be more easily fed into the pressure chamber with less resulting damage.Type: GrantFiled: November 15, 1993Date of Patent: May 2, 1995Inventor: Rudolph J. Fay

Patent number: 5297947Abstract: A rotary die moulding machine used in the commercial production of baked goods, which includes plastic inserts for the moulding cavities on the die roll, is disclosed. Each moulding cavity is formed as a bore with a first wall section extending inwardly from the outer surface of the die roll a depth corresponding to the desired thickness of the baked good being moulded, and a second wall section with an undercut edge beneath the first wall section. The plastic insert has a face portion with a designed face for imprinting a design into the dough, and has a base portion with a protruding edge which conforms to the undercut edge of the second wall section. The plastic insert fits snugly by snap action into the moulding cavity. The plastic insert further provides improved release of bakery dough. The plastic insert and the moulding cavity may be modified to accommodate different shapes, thicknesses and designs of commercially produced cookies, biscuits and other baked goods.Type: GrantFiled: May 5, 1992Date of Patent: March 29, 1994Assignee: Tiefenthaler Machinery Co., Inc.Inventor: Joseph Cardinali

Patent number: 5288220Abstract: A distinctive apparatus for contouring a fibrous web includes a supplying mechanism for providing a fibrous web which defines an interconnected series of appointed article segments along a length dimension of the web. A conveying mechanism moves the web at a selected speed along an appointed machine direction. A scarfing mechanism removes predetermined quantities of fibers from selected regions of the fibrous web. The scarfing mechanism is constructed to provide each of the article segments with a selected contoured basis weight which varies at least along the length dimension of the segment in a selected correspondence with a predetermined scarfing pattern. The scarfing pattern is provided by an outer peripheral surface of the scarfing mechanism, and the pattern is configured to have a selected variation at least along a movement direction of the scarfing mechanism.Type: GrantFiled: October 2, 1992Date of Patent: February 22, 1994Assignee: Kimberly-Clark CorporationInventors: Joseph M. Kugler, Peter J. Krautkramer, Lyle T. Lamers, Douglas P. Rammer

Patent number: 5205106Abstract: A rolled food item is fabricated by advancing food (14) and a sheet of support material (16) between the rollers (18, 20) of a strip sheeter (12) where the food (14) fills grooves (24) of the first roller (18) to deposit the food (14) in continuous strips on the support material (16). After passing through a cooling tunnel (58), the support material (16) is also cut into strips between the strips of food (14) in a first cutting section (62). The multiplicity of strips are then cut to lengths in a second cutting section (64). Labels (68) are secured to the trailing ends of the strips and the trailing ends of the strips are pressed by a label presser (70) to adhere the labels (68) to the strips. The strips are simultaneously rolled in a roll-up section (74) including a rotatable fork (76). Specifically, after the leading ends of the strips are inserted between the legs (78, 80) of the fork (76), the fork (76) is rotated to roll the strips on the fork (76).Type: GrantFiled: March 4, 1991Date of Patent: April 27, 1993Assignee: General Mills, Inc.Inventors: Craig E. Zimmermann, Rene K. Merle

Patent number: 5198233Abstract: An apparatus is disclosed for producing granules or pastils from a flowable material of varying viscosity wherein material is supplied to a pressing nip between a rotating hollow roll (1) having internal teeth and an externally toothed ejection roll (2) in engagement with said hollow roll. Provided in the hollow roll (1) are bores (5) which extend from the respective teeth bottoms of the internal toothing to the outer side of the hollow roll (1) and through which the material is expelled on engagement of the ejection roll (2) and deposited in the form of pastils or granules on a cooling surface (13). On the outer periphery of the hollow roll (1) a jacket tube (3) may be positioned the jacket tube having bores which align with the bores (5) of the hollow roll (1), the jacket bores also having a reduced cross-section compared with the bores of the hollow roll to permit adaption of the apparatus to the viscosity of the flowable material to be processed.Type: GrantFiled: December 5, 1990Date of Patent: March 30, 1993Inventor: Herbert Kaiser

Patent number: 5064584Abstract: A rotary molding apparatus has a die roll and a split clamping pillow block structure of self-centering structure supporting the opposite shaft ends of the die roll. The split pillow block has a pivotally mounted portion and a device for locking that portion when the die roll is in operation. A feed roller is mounted on upright arms which are urged toward the die roll. The arms carry doctor blade structure between the feed roller and the die roll and the doctor blade is biased toward the die roll. A fluent material supply hopper cooperates with the feed roller and there is a guide structure for effecting movement of the hopper between the feed roller cooperation position and a backed-off position. A magazine is provied for storing a plurality of die rolls and a mechanism is provided for selecting any die roll from the magazine and for transporting such die roll from the magazine into working position in the pillow blocks and for selectively returning the die roll to the magazine.Type: GrantFiled: September 14, 1989Date of Patent: November 12, 1991Assignee: Weidenmiller CompanyInventor: Frederick W.
