Claims (10)

1. Способ крепления многосекционного оголовья к лицевой маске, содержащий операции: подготовки заготовки лицевой маски, имеющей левое и правое места крепления оголовья, причем заготовка лицевой маски имеет трассу оголовья, проходящую между левым и правым местами крепления оголовья; позиционирования материала оголовья вдоль трассы оголовья; прикрепления материала оголовья по меньшей мере к одному из левого и правого мест крепления и формирования по меньшей мере одной продольной линии надреза в материале оголовья, причем по меньшей мере одна продольная линия надреза определяет по меньшей мере двухсекционное оголовье.A method for attaching a multi-section headband to a face mask, comprising the steps of: preparing a face mask blank having left and right headband attachment points, the face mask blank having a headband path extending between the left and right headband attachment points; positioning the headband material along the headband path; attaching the headband material to at least one of the left and right attachment points and forming at least one longitudinal notch line in the headband material, wherein at least one longitudinal notch line defines the at least two-section headband. 2. Способ по п.1, отличающийся тем, что операцию формирования по меньшей мере одной продольной линии надреза осуществляют до операции прикрепления материала оголовья по меньшей мере к одному из левого и правого мест крепления. 2. The method according to claim 1, characterized in that the operation of forming at least one longitudinal notch line is carried out before the operation of attaching the headband material to at least one of the left and right attachment points. 3. Способ по пп. 1-2, отличающийся тем, что материал оголовья содержит по меньшей мере один непрерывный термопластичный поверхностный слой, прикрепленный по меньшей мере к одной эластомерной сердцевине, причем материал оголовья имеет первый модуль упругости в неактивированном состоянии и второй, более низкий, модуль упругости в активированном состоянии, а термопластичный поверхностный слой образует микротекстурированный остаточно деформированный поверхностный слой, когда материал оголовья находится в активированном состоянии. 3. The method according to PP. 1-2, characterized in that the headband material contains at least one continuous thermoplastic surface layer attached to at least one elastomeric core, the headband material having a first elastic modulus in an inactive state and a second, lower elastic modulus in an activated state and the thermoplastic surface layer forms a microtextured residually deformed surface layer when the headband material is in the activated state. 4. Способ по п.3, отличающийся тем, что эластомерная сердцевина и по меньшей мере один термопластичный слой находятся в непрерывном контакте в активированном состоянии. 4. The method according to claim 3, characterized in that the elastomeric core and at least one thermoplastic layer are in continuous contact in an activated state. 5. Способ по пп. 3 и 4, отличающийся тем, что он дополнительно включает операцию активации растяжением по меньшей мере части материала оголовья, осуществляемую после операции прикрепления материала оголовья. 5. The method according to PP. 3 and 4, characterized in that it further includes the operation of activation by stretching at least part of the material of the headband, carried out after the operation of attaching the material of the headband. 6. Лицевая маска, изготовленная способом по пп. 1-5. 6. The facial mask made by the method according to paragraphs. 1-5. 7. Многосекционное оголовье, прикрепляемое к заготовке лицевой маски, причем заготовка лицевой маски имеет левое и правое места крепления, определяющие трассу оголовья, а многосекционное оголовье содержит материал оголовья, простирающийся вдоль трассы оголовья между левым и правым местами крепления, при этом материал оголовья имеет по меньшей мере одну продольную линию надреза, причем по меньшей мере одна продольная линия надреза определяет по меньшей мере двухсекционное оголовье. 7. A multi-section headband attached to the face mask blank, the face mask blank having left and right attachment points defining the headband path, and the multi-section headband contains headband material extending along the headband path between the left and right attachment points, wherein the headband material has at least one longitudinal notch line, and at least one longitudinal notch line defines at least a two-section headband. 8. Изделие по п.7, отличающееся тем, что материал оголовья содержит по меньшей мере один непрерывный термопластичный поверхностный слой, прикрепленный к эластомерной сердцевине, причем материал оголовья имеет первый модуль упругости в неактивированном состоянии и второй, более низкий, модуль упругости в активированном состоянии, а термопластичный поверхностный слой образует микротекстурированный остаточно деформированный поверхностный слой, когда материал оголовья находится в активированном состоянии. 8. The product according to claim 7, characterized in that the headband material contains at least one continuous thermoplastic surface layer attached to the elastomeric core, the headband material having a first elastic modulus in an inactive state and a second, lower elastic modulus in an activated state and the thermoplastic surface layer forms a microtextured residually deformed surface layer when the headband material is in the activated state. 9. Изделие по п. 8, отличающееся тем, что эластомерная сердцевина и по меньшей мере один термопластичный слой находятся в непрерывном контакте в активированном состоянии. 9. The product according to claim 8, characterized in that the elastomeric core and at least one thermoplastic layer are in continuous contact in the activated state. 10. Изделие по пп. 7-9, отличающееся тем, что материал оголовья разделен вдоль по меньшей мере одной продольной линии надреза для образования двухсекционного оголовья. 10. The product according to paragraphs. 7-9, characterized in that the headband material is divided along at least one longitudinal notch line to form a two-section headband.
