摘要:
The invention relates to a method for producing a bottle having a sheath made of a shrinkable plastic film, the bottle comprising, on the circumferential surface thereof, at least one handle recess or handle opening projecting into the interior of the bottle, comprising the following steps: producing a tube from the shrinkable plastic film; drawing the tube onto the bottle; shrinking the plastic film onto the bottle; laser-cutting the area of the shrinkable plastic film which covers the handle recess or handle opening of the bottle; and sucking away the cut-out area by means of a fan.

There is provided a film opening mechanism in which, regardless of whether a tubular film is long or short, a deviation in timing of delivery of the tubular film from a mandrel does not occur, and the tubular film does not become wrinkled. The film opening mechanism includes a mandrel 30 for causing the tubular film F to be opened into a predetermined state by fitting it thereon; a film transport unit 40 composed of an upstream-side feed belt unit 40A and a downstream-side feed belt unit 40B, each having a feed belt 46 which nips the tubular film F fitted on the mandrel 30 in cooperation with the mandrel 30 to transport the tubular film F toward a lower side of the mandrel 30; and attraction means for attracting the mandrel 30 and the feed belt 46 to each other by means of a magnetic attractive force. The attraction means is composed of a permanent magnet embedded in a portion of the mandrel 30 in which the tubular film F is nipped by the feed belt 46 and a steel core embedded in the feed belt 46.

A method for producing roller means (1) comprises providing a base structure (2) and coating said base structure (2) with tubular means (3), by fitting on said base structure (2) said tubular means (3); a method for producing tubular means (3) comprises injecting flowable means into a cavity (30) defined inside mould means (23), said flowable means being suitable for forming said tubular means (3), and further comprises solidifying said flowable means; between said mould means (23) and said tubular means (3) separator means are inserted (28), said separator means being suitable for enabling said tubular means (3) to be detached from said mould means (23); an apparatus for producing tubular means (3) comprises mould means (23) suitable for receiving flowable means arranged for forming said tubular means (3) and separator means (28) suitable for enabling said tubular means (3) to be detached from said mould means (23).
摘要:
Der Rohrkörper besteht aus mehreren ineinander gesteckten Hohlkörpern (12,13,14,15), von denen jeder schraubenförmig gewickelte Verstärkungsfasern enthält. Beide Hohlkörper sind an einem Ende miteinander verbunden und dann gegeneinander verdreht und am gegenüberliegenden Ende ebenfalls miteinander verbunden. Auf diese Weise sind die Hohlkörper (12,13,14,15) mit einem Torsions-Vorspannmoment versehen. Das Vorspannmoment kann so bemessen werden, dass die einzelnen Faserlagen proportional mit dem Drehmoment (T) bis zur jeweiligen maximal zulässigen Spannung belastet werden. Dadurch wird erreicht, dass der faserverstärkte Werkstoff in allen Raumrichtungen einer Belastung unterliegt, die proportional zur richtungsabhängigen Festigkeit des Werkstoffs ist.
摘要:
A tube-covered article that can reduce a space for storing a tubular cover member for covering an article with a tubular cover member so as to realize a saving in resources, while mounting a tube with excellent performance even in a narrow space. The invention provides a cylindrical tube-covered article, in which the tubular cover member (2) covers the article (5) as a result of room temperature recovery thereof after withdrawing a cylindrical support (1), the tube having a length larger than the cylindrical support, and an inner diameter approximately equal to or smaller than the outer diameter of the article (5) to be covered. The tube (2) is expanded around the periphery of the support (1) and collapsibly folded along the longitudinal direction thereof before application to the article (5).
