Abstract: The present invention relates to a method and an apparatus for controlling the drafing of sliver in a draw frame in which sliver first travels through an advance sensing means that senses variations in the mass, then passes through a drafting means which is located after the advance sensing means and is provided with an adjustable draft, and finally travels through an after sensing means located after the drafting means which senses the mass per unit of length, whereby the draft of the drafting means is varied to compensate for variations in mass of sliver in response to the sensed variations in mass evaluated in a time-delayed manner and of the difference of the measured mass per unit length of the output and of a selectable theoretical value for the mass per unit of length.

Abstract: A carding machine includes a licker-in and a waste separator cooperating therewith. The waste separator includes first and second plates arranged consecutively along a periphery of the licker-in. The first and second plates are spaced from one another by a clearance constituting a waste outlet opening through which waste is discharged with the aid of a circumferential air stream generated by the rotation of the licker-in. The first and second plates each have a pivotally supported end for adjusting their angular position, whereby a radial distance from the periphery of the licker-in is varied for controlling the discharge of waste through the outlet opening. A nozzle is arranged at the licker-in at a location generally diametrically opposite the waste outlet opening. The nozzle has an outlet aperture merging into a space situated immediately radially outwardly of the periphery of the licker-in.

Abstract: An athletic garment particularly suitable for hockey players protects the genital area of the wearer. The garment comprises a waistband which is supported at the wearer's waist elastically and with a drawstring. An inner pant and an outer pant are attached the waistband. The inner pant has a rise so selected that its crotch portion engages and supports the genital area of the wearer. The outer pant has a pocket adjacent its crotch portion which receives a genital protector. The pocket is positioned to overlay the genital area when the waistband is maintained at the wearer's waist thereby ensuring proper protection. The outer pant has a larger rise than the inner pant so that the pocket is normally spaced from the wearer's genital area, providing greater comfort and enhanced freedom of movement. Hook-type Velcro.TM. fasteners are positioned on the front and back of each pant leg associated with the outer pant and serve to support hockey stockings.
