may be able to engage and pull the nonwoven tube 704 two wheels 708 on each arm 715 as shown in fig1 may afford a safer accommodation for the rotating tube 704 fig1 illustrates the puller wheels 708 on one of the puller arms 715 the puller wheels 708 include four rollers 709 each of which is shaped as a prolate spheroid that rotates about its own major longitudinal axis the structural details of the wheel 708 and the rollers 709 are shown in fig1 as shown in fig1 the drive axle 710 of the puller arm wheels 708 is surrounded by a multi spoke hub 711 the hub 711 and the axle 710 may be secured by a key or tab each roller 709 rotates around a rod shown in dashed lines that is positioned through a pair of adjacent spokes in the hub 711 since each roller 709 has its own axis of rotation i e about the rod each roller 709 can rotate independently of the other rollers 709 while the collective profile of the rollers 709 produces a wheel or circular shape conducive for engaging the tubular nonwoven 704 the rollers 709 may be made of or covered with a semi hard material to avoid slippages and scratches on the tubular nonwoven 704 providing grooves in the roller surface as shown in fig1 or roughing up the surface of the roller can also improve traction fig1 17 and 18 illustrate alternate multi directional wheel assemblies 712 that can be used as the.
