===Carding engine===
[[Lewis Paul]] had invented a machine for [[carding]] in 1748. Arkwright made improvements to this machine and in 1775 took out a patent for a new carding engine, which converted raw cotton to a continuous skein prior to spinning.<ref name="Povijest 12">{{cite book |editor1=[[Ivo Goldstein]]  |editor2= Kristina Milković |editor3= Enrico Craveto |location= [[Zagreb]] |date=n.d. |orig-date=2008 |title=Povijest 12: kolonijalizam i građanske revolucije |publisher=[[Europapress holding]] |page=67 |translator=Ana Bedurina |language= hr |isbn=978-953-300-046-6 }}</ref>
The machine used a succession of uneven rollers rotating at increasingly higher speeds to draw out the [[roving]], before applying a twist via a bobbin-and-flyer mechanism. It could make cotton [[yarn|thread]] thin and strong enough for the warp threads of [[Textile|cloth]].
