(57) The invention is characterised in that it comprises a textile insert (1) which is
completely permeated by and embedded in the mixture (2) and is made inseparable from
the latter by means of moulding and vulcanisation in an injection-moulding press with
a closing pressure of approximately 200 atmospheres. This insert is embedded in the mixture in an asymmetrical manner, as a result of which
externally the insert is covered with a thick layer of rubber, whereas internally
the mixture permeates beyond the insert on account of the moulding pressure and reaches
a reduced thickness of 0.1mm. Thus, unlike those of the prior art, anti-NBC overshoes
are obtained which have an ergonomic shape, are without joints, and hence are practically
impermeable to NBC aggressive agents, and which have excellent mechanical characteristics. They are used, in particular, for protection against the attacks of chemical, biological
and bacteriological agents and for protection against thermonuclear radiation.
