Abstract
A process for continuous and repetitive production of discrete articles of a desired cross-section from a deformable material can be effected by introducing the material into a moving passageway, causing the material to be drawn along the passageway by frictional drag, and, by blocking the passageway, compressing the material and causing it to enter into successively presented chambers shaped to produce articles of the desired configuration. Optionally the articles can be ejected from said chambers to enable the latter to be re-used. Apparatus for performing this process is also disclosed.

A process for the continuous and repetitive production of discrete articles of a desired cross-section from a deformable material, comprising the steps of
- introducing the material into a moving and confined passageway,
- causing the material to be drawn along the passageway by frictional drag of the moving passageway, and
- by blocking said passageway at a position spaced from the position of introduction of the material, compressing said material and causing it to enter into successively presented chambers shaped to produce articles of the desired configuration.
Apparatus for the continuous and repetitive production of discrete articles of a desired cross-section from a deformable material, such apparatus comprising a passageway for receiving the deformable material and defined by a first, rotatable member having a groove providing the floor and both sides of the passageway, and a second, relatively stationary, member projecting into said groove and providing the roof of the passageway, chambers positioned so as to be successively presentable to material drawn along said passageway by frictional drag, and an abutment for blocking said passageway whereby the material is compressed and is caused to enter into said chambers in succession and is formed into articles in said chambers.
Apparatus for the continuous and repetitive production of discrete articles of a desired cross-section from a deformable material, such apparatus comprising a passageway for receiving the deformable material and defined by a first, rotatable member having a groove providing the floor and both sides of the passageway, and a second member projecting into said groove and providing the roof of the passageway, said second member being also rotatable in the same plane as said first member but about an axis spaced from the axis of rotation of said first member such that its periphery projects into said groove to form the roof of said passageway and to provide that the passageway has a decreasing cross-sectional area along its effective length, chambers positioned so as to be successively presentable to material drawn along said passageway by frictional drag, and an abutment for blocking said passageway whereby the material is compressed and is caused to enter into said chambers in succession and is formed into articles in said chambers.
