Abstract: Изобретение относится к изготовлению эластомерной пленки, которая содержит поверхностные участки по меньшей мере двух эластомерных материалов, в частности двух различно окрашенных полиуретановых материалов. В способе изготовления эластомерной пленки экранируют участок поверхности формы при помощи маски, которая имеет по меньшей мере один край, ограничивающий указанный участок. Напыляют слой первого эластомерного материала на поверхность формы и на край маски. Затем маску удаляют и производят напыление второго эластомерного материала на указанный участок поверхности формы. При экранировании участка поверхности формы край маски размещают сверху по меньшей мере на одном выступающем крае поверхности формы, который совместно с краем маски ограничивает участок поверхности формы. Первый слой эластомерного материала напыляют на одну из сторон выступающего края поверхности формы. По второму варианту при напылении первого эластомерного материала край маски устанавливают на определенном расстоянии от поверхности формы, чтобы избежать контакта между слоем первого эластомерного материала, напыленного на поверхности формы, и маской. Блок напылительной формы содержит форму с ограничивающей поверхностью и по меньшей мере одну маску для экранирования участка поверхности формы. Маска имеет по меньшей мере один край, ограничивающий этот участок. Поверхность формы имеет по меньшей мере один выступающий край, ограничивающий совместно с краем маски указанный участок поверхности формы. Край маски имеет возможность размещения сверху на выступающем крае формы.
