Abstract
An apparatus (1) and method for fibre processing, in particular, for opening and drafting fibres. The apparatus includes a device (2) having a series of pins (7) coupled to a drive mechanism (8) and arranged for sequential insertion in a feed path (6) along which the fibres are passed, the mechanism being arranged to increase the relative speed between the pins after insertion, to open and draft the fibres.
Claims17
An apparatus for fibre processing, having a fibre-opening device including a series of pins coupled to a drive mechanism and arranged for sequential insertion in a feed path along which the fibres are passed, the mechanism being arranged to increase the relative speed between the pins after insertion.
An apparatus as claimed in any one of the preceding claims, wherein the drive mechanism drives the pins along a drive path which includes a curved portion to increase the relative angle therebetween.
An apparatus as claimed in any one of the preceding claims, including a plurality of devices arranged in series.
A method for opening and drafting fibres including passing the fibres along a feed path to be engaged by a series of pins coupled to a drive mechanism, for sequential insertion into the feed path, and increasing the relative speed between the pins after insertion in the feed path.
