A method for preparing continuous bamboo fibers, which relates to a technical field of bamboo fiber preparation. The method includes processing bamboo raw materials into reticulated bamboo fiber strips, screening the bamboo fiber strips, dividing the reticulated bamboo fiber strips with different properties according to product requirements, performing high pressure splitting on the reticulated bamboo fiber strips which conforms to a screening condition, separating the bamboo fibers with different slenderness ratios from the bamboo fiber strips after the high pressure splitting is performed, forming a partial oriented bamboo fiber mat with uniform density by the bamboo fibers, forming an oriented bamboo fiber bundle with uniform linear density by the bamboo fiber mat, twisting the bamboo fiber bundle to form a bamboo fiber yarn, forming a rope by the bamboo fiber yarn, and forming a spindle based on a specifications.

In a drafting system (1) for a textile machine, in particular an air-spinning machine, for drafting a strand-shaped fibre band fed to the drafting system, having a plurality of roller pairs arranged in succession in a running direction (A) of the fibre band and each having a top roller (3) and a bottom roller (4), and a weighting device for applying a load to the top roller (3) of the plurality of roller pairs; wherein the respective bottom roller (4) is mounted and held in a housing (2) of the drafting system (1), wherein the respective top roller (3) is mounted and held in the housing (2) of the drafting system (1) by means of a top roller carrier (30) which can be pivoted about a rotary axis.

A method for preparing continuous bamboo fibers, which relates to a technical field of bamboo fiber preparation. The method includes processing bamboo raw materials into reticulated bamboo fiber tapes, screening the bamboo fiber tapes, dividing the reticulated bamboo fiber tapes with different properties according to product requirements, performing high pressure splitting on the reticulated bamboo fiber tapes which conforms to a screening condition, separating the bamboo fibers with different slenderness ratios from the bamboo fiber tapes after the high pressure splitting is performed, forming a partial oriented bamboo fiber mat with uniform density by the bamboo fibers, forming an oriented bamboo fiber bundle with uniform linear density by the bamboo fiber mat, twisting the bamboo fiber bundle to form a bamboo fiber yarn, forming a rope by the bamboo fiber yarn, and forming a spindle based on a specifications.

An autoleveller draw frame includes a drafting system having a plurality of roller combinations. A drive unit configured with the plurality of roller combinations has a main motor that drives a first roller combination at a constant main rotational speed. A regulating motor regulates a rotational speed of a second roller combination wherein, due to the regulation, the rotational speed of the second roller combination is changeable from a basic rotational speed into an autolevelling speed. The basic rotational speed depends on the main rotational speed and the autolevelling speed is independent of the main rotational speed, wherein the drafting of the fibrous web is adjustable. The regulating motor is drive-independent of the main motor to drive the second roller combination at the autolevelling speed according to an electrical signal that is based on the main rotational speed.
