Abstract
Textile slivers tend to loose their cohesion when travelling over long distances from one piece of storage or processing equipment to another such piece of equipment. This problem is overcome by subjecting the sliver to a false twisting process during its travel, desirably by a pneumatic false twister located immediately adjacent to the sliver-receiving equipment.

A method of handling a silver, comprising continuously applying mechanical tension to the sliver for taking the sliver from a first piece of sliver storage or processing equipment and for causing the sliver to travel a substantial distance into the control of a spaced second piece of sliver storage or processing equipment, and continuously directing a stream of gas toward the silver intermediate the first and second pieces of equipment for continuously pneumatically forming a false twist in the sliver for increasing the strength and cohesion of the sliver during its travel between the first and second pieces of equipment by effecting a temporary increase of interfiber friction in the sliver and for simultaneously removing impurities from the sliver, without said stream of gas contributing substantially to movement of the sliver in longitudinal direction.
Apparatus for handling a sliver, comprising a first piece of sliver storage or processing equipment, a second piece of sliver storage or processing equipment spaced a substantial distance from said first piece of equipment, means defining a path of travel for said sliver between said first and second pieces of equipment, means for continuously applying mechanical tension to the silver to cause it to travel along said path and means for temporarily increasing the strength and cohesion of the sliver during its travel between the first and second pieces of equipment, said means comprising a false twister device arranged along said path of travel for continuously subjecting the sliver to a false twisting process in order to effect a temporary increase of interfiber friction in the sliver, said false twister device comprising pneumatic means for supplying a gas under pressure to the sliver for imparting a temporary twist to the sliver and for simultaneously cleaning the sliver without contributing substantially to movement of the sliver in longitudinal direction.
