Description
Schlagstock für Unterschlag-Webstühle
Die vorliegende Erfindung betrifft einen Schlagstock für Unterschlag-Webstühle.
Bisher wurden diese Schlagstöcke ausschliesslich aus gewachsenem Holz oder aus verleimtem Sperrholz hergestellt. Es hat sich gezeigt, dass derartige Schlagstöcke sehr spröde sind und eine relativ kurze Lebensdauer aufweisen. Diese Nachteile können behoben werden, wenn man die Schlagstöcke erfindungsgemäss aus Kunststoff herstellt. Als Material hierfür kommt z. B. Polyamid in Frage, welches mit Glasfasern armiert sein kann.
Auch Polyäthylene eignen sich für diesen Zweck sehr gut. Vornehmlich Niederdruck-Polyäthylene mit einem Momekulargewicht von 500 000 und mehr.
Solche Stöcke können direkt zum Schlagen des Schützen verwendet werden. Die bisher üblichen Picker, welche zwischen Schützen und Schlagstock angeordnet waren, können wegfallen.
Der Schlagstock aus Kunststoff kann auch am obern Ende, wo er die Schützenspitze trifft, eine Verstärkung aufweisen, die auswechselbar sein kann.
Die Verstärkung aus Kunststoff kann auch auf den Kunststoffschlagstock aufgeschweisst sein. An der Stelle, an der die Schützenspitze aufschlägt, kann auch im Schlagstock eine zur Schützenspitze passende Ausnehmung angebracht sein.
Für derart ausgebildete Schlagstöcke können Schützen mit Spitzen, die ebenfalls aus Kunststoff bestehen, Verwendung finden.
Bisher waren sämtliche Schützen mit Spitzen aus Metall versehen, welche das Gewicht erhöhten und die Aufschlagstelle zerstörten, oder aber mit solchen aus Holz. Holzspitzen nützen sich aber rasch ab.
Durch die Verwendung von Schützen mit Spitzen aus Kunststoff in Zusammenarbeit mit einem Schlagstock aus Kunststoff wird der Schlagmechanismus leichter, einfacher, dauerhafter und betriebssicherer.
PATENTANSPRUCH
Schlagstock für Unterschlag-Webstühle, dadurch gekennzeichnet, dass er aus Kunststoff besteht.
UNTERANSPRÜCHE
1. Schlagstock nach Patentanspruch, dadurch gekennzeichnet, dass er aus Polyamid besteht.
2. Schlagstock nach Patentanspruch, dadurch gekennzeichnet, dass er aus mit Glasfasern armiertem Polyamid besteht.
3. Schlagstock nach Patentanspruch, dadurch gekennzeichnet, dass er aus Polyäthylen besteht.
4. Schlagstock nach Patentanspruch, dadurch gekennzeichnet, dass er aus Polyäthylen mit einem Molekulargewicht von mindestens 500 000 besteht.

Baton for underlay looms
The present invention relates to a baton for underlay looms.
Up until now these batons were made exclusively from natural wood or glued plywood. It has been shown that such batons are very brittle and have a relatively short service life. These disadvantages can be eliminated if the batons are made of plastic according to the invention. As a material for this comes z. B. polyamide in question, which can be reinforced with glass fibers.
Polyethylenes are also very suitable for this purpose. Mainly low-pressure polyethylene with a molecular weight of 500,000 and more.
Such sticks can be used directly to hit the shooter. The previous pickers, which were arranged between the shooter and the baton, can be omitted.
The plastic baton can also have a reinforcement at the upper end, where it meets the point of the shooter, which can be exchangeable.
The plastic reinforcement can also be welded onto the plastic baton. At the point where the point of the shooter hits, a recess that matches the point of the shooter can also be made in the baton.
For batons designed in this way, shooters with tips that are also made of plastic can be used.
So far, all shooters have been provided with tips made of metal, which increased the weight and destroyed the point of impact, or with tips made of wood. However, wooden points wear out quickly.
By using shooters with plastic tips in conjunction with a plastic baton, the striking mechanism becomes lighter, simpler, more durable and more reliable.
PATENT CLAIM
Baton for underlay looms, characterized in that it is made of plastic.
SUBCLAIMS
1. baton according to claim, characterized in that it consists of polyamide.
2. baton according to claim, characterized in that it consists of polyamide reinforced with glass fibers.
3. baton according to claim, characterized in that it consists of polyethylene.
4. baton according to claim, characterized in that it consists of polyethylene with a molecular weight of at least 500,000.
