Abstract: A textile card crush roll operating system is driven by a two-speed electric motor completely independent of the main card cylinder driving motor and is provided with starting control means for operating the crush roll motor at slow speed for a pre-determined time according to automatically operable timing means during which interval sliver from the crush rolls is manually fed into an associated coiler and arranged in such a way that tension of the sliver is applied to stop control means which stops operation of the two-speed crush roll motor after the motor is accelerated to its high speed condition under the control of operating control means. Thus if sliver tension is substantially reduced, the crush roll system is automatically shut down.

Abstract: A unitary wrapper blank having top, bottom and side walls interconnected to form a tubular structure about a plurality of articles incorporates one composite wall formed of a pair of overlapping panels one of which incorporates at least one specially configured locking slit which receives a specially configured locking tab struck from the other lap panel after the locking tab is folded out of the plane of the other panel along a hinge line and into flat face contacting relation with an adjacent positioning tab formed on an edge of the other panel which tab also is inserted along with the locking tab into the locking slit. After the positioning tab and locking tab are fully inserted into the locking slit, the locking tab swings away from the positioning tab due to its inherent bias which tends to swing the locking tab into the plane of the panel from which it is struck.
