US 10,299,438 B2 · Apparatus for forming and wrapping material

Abstract

A forming and wrapping unit and method for forming material into a continuous bar and wrapping the material. The unit including a forming chamber for forming material into a continuous bar, a sheet wrapping device for wrapping the continuous bar, and a controller operating on the sheet wrapping device. The sheet wrapping device and the controller are adapted to be operable independently of a rate of feeding bulk material into the forming chamber. The method includes feeding material to a wrapping position while forming the material, wrapping a sheet around the material such that the sheet at least partly overlaps a previously wrapped portion of the sheet, and transferring the wrapped material from the wrapping position to a storage ready position. The feeding of the material to a wrapping position and wrapping a sheet around the material are separately operable.

Dependent claims

A forming and wrapping unit for forming material into a continuous bar and wrapping said material, and adapted to be attached to a material providing unit, comprising:

a forming chamber for forming said material into said continuous bar, said forming chamber having an inlet opening for feeding said material into said forming chamber and an outlet opening for discharging said continuous bar;
a sheet wrapper configured to wrap said continuous bar with a plastic wrapping material;
at least one wire attached to a front wall of said forming and wrapping unit, said at least one wire arranged to be embedded into said continuous bar during wrapping of said continuous bar;
and
a second regulator configured to operate said sheet wrapper independently of a rate of feeding material into said forming chamber such that said sheet wrapper wraps a first part of said continuous bar with a first predetermined number of layers of wrapping material and a second part of said continuous bar with a second predetermined number of layers of wrapping material,
wherein a speed of said sheet wrapper is based on a measured release rate of said at least one wire.
