Description
Ruhrchemie Aktiengesellschaft, Oberhausen-Holten Kegelspiel aus hochmolekularem Polyäthylen Die für ein Kegelspiel erforderlichen Einzelteile, wie Kegel, auch Kegelhölzer genannt, und Kugeln sind bei ihrer Benutzung der stärksten Beanspruchung durch Stoß und Schlag ausgesetzt. Ruhrchemie Aktiengesellschaft, Oberhausen-Holten Skittles made of high molecular weight Polyethylene The individual parts required for a game of skittles, such as skittles and skittles called, and balls are the most exposed to impact when they are used and exposed to blow.
Das bis jetzt fast ausschließlich für ihre Herstellung verwendete Holz weist selbst als Hartholz nicht immer die große Widerstandsfähigkeit und Splitterfestigkeit auf, die der ständig wiederholten Beanspruchung gewachsen ist.That up to now has been used almost exclusively for their production Even as hardwood, wood does not always have great resilience and splinter resistance that can cope with the repeated use.
Es hat sich gezeigt, daß sowohl Kegel (Fig. l) als auch Kugeln (Fig.
2) aus hochmolekularem Polyäthylen mit einem Molekulargewicht von mehr als 100 000
für das Kegelspiel besonders gut geeignet sind. Während hölzerne Kegel bei dem immer
wiederkehrenden Anprall der Kugeln zum Splittern neigen, so daß weder ihre Form
noch ihr Gewicht dauernd erhalten bleibt, zeigen die aus hochmolekularem Polyäthylen
hergestellten Kegel sich völlig unempfindlich und unveränderlich. Ebenso beweisen
Kugeln zum Kegelspiel, die aus hochmolekularem Polyäthylen hergestellt werden, eine
absolute Splitterfestigkeit, die eine Dauerbeständigkeit der Kegelform ohne die
geringste Abweichung garantiert. Überdies lassen sich solche Kugeln leichter abwerfen,
in ihrem Gang besser dirigieren und leichter mit "Effet"versehen, wie der Kegler
sagt, d. h. mit dem gewünschten Drall, so daß sich bestimmte Kegler-Effekte leichter
bewerkstelligen lassen.
