Device to process a plurality of fiber slivers

A device for processing a plurality of fiber slivers, said device utilizing drawing-in cylinders for joint feed of fiber slivers into said device, said device comprising a funnel for uniting the fiber slivers into a fiber amalgam as the fiber slivers pass therethrough, said funnel including horizontal surfaces and lateral surfaces defining a passage opening into said funnel, said lateral surfaces being adjustable relative to said horizontal surfaces so that the total effective cross-sectional area of said passage opening presented to the fiber slivers is adjustable depending on the degree of compression of the fiber slivers desired, said device further comprising lateral elements defining said lateral surfaces, said funnel comprising a cover supported above said adjustable lateral elements, said lateral surfaces being adjustable below and relative to said cover so that said passage opening is defined by said cover and said lateral surfaces, the degree of movement of said lateral surfaces relative said cover being defined by oblong holes defined in said cover, said oblong holes engaged by attaching devices for attaching said lateral elements to said cover.

A funnel for use with a sliver fiber processing machine, said funnel for condensing a plurality of fiber slivers into a fiber amalgam as the fiber slivers pass therethrough, said funnel comprising horizontal surfaces and adjustable lateral surfaces defining a passage opening into said funnel, said adjustable lateral surfaces adjustably configured so that the total effective cross-sectional area of said passage opening presented to the fiber slivers is adjustable depending on the degree of compression of the fiber slivers desired, said funnel further comprising adjustable lateral elements, said lateral elements defining said lateral surfaces, said funnel comprising a cover supported above said adjustable lateral elements, said lateral surfaces being adjustable below and relative to said cover so that said passage opening is defined by said cover and said lateral surfaces, the degree of movement of said lateral surfaces relative said cover being defined by oblong holes defined in said lateral elements, said oblong holes engaged by attaching devices for attaching said lateral elements to said cover.
