A process and an equipment for cutting material comprehends the surrounding at least of one, however preferably of several round knives along the inner wall of a drum. The adjacent round knives have a predetermined uniform axial distance as well as angular distance referred to the axle of the drum, at which it concerns a rotating hollow cylinder.

Process and equipment for cutting material

A process for cutting of material includes the continuous loading therefrom into a generally cylindrically or conically shaped vessel, which is rotating around its longitudinal axis, in which is mounted a fast rotating knife shaft, its knives which are provided with one or several cutting edges reach near to the inside wall of the vessel. The material to be cut, loaded into the vessel in axial direction, deposits a layer on the inside wall of the vessel in consequence of the centrifugal force, which is treated by the knives and is displaced in axial direction to the discharging end of the vessel where the cut material is continuously taken away. The equipment includes a material feeding device, a drive for the vessel and the knife shaft, each with different speed, as well as a discharging device for the cut material. The axis of the rotating vessel as well as of the knife shaft can be vertically or horizontally arranged.

Process and equipment for continuous cutting of material

A packaging device for sealingly closing an upper foil and a lower foil utilizing a framelike constructed welding device which has a separate drive for welding together the lower and the upper foil, of which at least the lower foil is formed into containerlike segments and is moved, held by a chain at the sides thereof, through the packaging device. The packaging device has an evacuating chamber which is formed of two boxlike halves, of which one half is stationary and the other half is vertically movable. One of the halves has a framelike welding device embodied therein.
