  A special class of braids, called woven, is introduced and it is shown that
every conjugation class of the braid group contains woven braids. In
consequence, links can be presented as plats or closures of woven braids.
Restricting on knots, we get the 'woven version' of the well-known theorem of
Markov, giving moves that are capable of producing all woven braids with
equivalent closures. As corollary we obtain that a link in which each component
is dyed with at least two colours can be projected onto a plane without
crossing strands of the same colour. Finally a table of minimal woven braids
for all nine crossing knots is appended.
