ABSTRACT:
The problem of sliver slingover encountered when starting up a coiler of a high speed drawframe or the like at full production rates can be obviated through this invention wherein for an initial interval the rotational axes of the can and its platform and of the fixed coiler tube are brought closer together than one would require to fill the can to maximum capacity from side to side so that the inertial momentum of the spewing sliver is insufficient to over extend the sliver beyond the can's rim; this condition in filling is maintained until a measured amount of sliver sufficient to produce a firm abutting of the topmost coils with the exit of the coiler tube and thus sufficient resistance to the then spewing sliver therefrom to contain the coils within the side to side extent of the can is attained, whereupon through a shifting mechanism, which may be pneumatically operable, the can platform and its axis are shifted a prescribed distance of greater separation away from the fixed coiler tube axis for the remainder of the can filling.
