  • Patent number: 8714067
    Abstract: Apparatus for cutting plural aligned ply strips includes plural knife blades disposed in a spaced manner such that each knife blade is aligned with and in closely spaced relation to an associated ply strip. The knife blades are pivotally mounted in a common housing and are coupled to a single rotational drive for allowing each knife blade to assume the same predetermined cutting angle relative to its associated ply strip, where the cutting angle may be varied between ±45°. The plural knife blades are coupled to a rotational drive by means of plural circular drive gears and are connected to a linear drive for displacing the knife blades into contact with the ply strips for cutting the strips at the predetermined angle. The severed edges of the aligned ply strips are formed in mutual linear alignment and do not include projecting triangular patterns, or crenelations.

  • Patent number: 7832313
    Abstract: A device for through-cutting of an extruded ice mass, which has a first knife which is reciprocably arranged in a transverse first plane immediately after the outlet of the nozzle and arranged with a first length of stroke and a second knife which is reciprocably arranged in a plane which is parallel to the first plane and which is arranged immediately below the first knife with respect to the flow direction out of the nozzle, the second knife is arranged with a second stroke length which is smaller than the first stroke length, and a control for producing simultaneous reciprocation of the first and the second knife. Hereby, a shearing is achieved which is more precise and commonly applicable for manufacturing of ice cream portions by an automated production of ice cream products.

  • Patent number: 5287781
    Abstract: A novel dough feeding, cutting and depositing apparatus is provided herein. It includes a pivotally-mounted feed tray. Means are provided on the feed tray for gripping a continuous dough sheet and for advancing it forwardly along the feed tray to the downstream end of the feed tray. Means are provided for cutting a discrete sheet of dough from a continuous dough sheet overlapping the end of the feed tray, and for depositing such discrete sheet of dough on a sheet of dough tray station. Means are provided for moving the upstream end of the feed tray upwardly to its maximum "up" position for the duration of the time the continuous dough sheet is being advanced forwardly along the feed tray. Means are provided for moving the upstream end of the feed tray downwardly to its maximum "down" position for the duration of the time the means for cutting is effecting the cutting of the continuous dough sheet into a discrete sheet of dough.

  • Patent number: 4941378
    Abstract: A continuously fed tube is momentarily halted at a cutting station and quickly cut by a rotating knife. The tube is continuously advanced from driving rollers to idler rollers and passes through interemdiate pinch rollers which are cam controlled in synchronism with the cutting process to bow the tube at a rate which causes the tube portion at the cutting station to briefly stop during cutting. The cutter includes a planetary gear set having a carrier rotatable about a central axis which carries a knife for rotation about another axis while it revolves about the central axis. The knife makes many rotations per carrier revolution but is in position to cut the tube during one of the rotations.
