Description

Die Erfindung bezieht sich auf eine Deckelgarnitur für eine Wanderdeckelkarde, auf einen Deckelstab mit einer entsprechenden Garnitur und auf eine Karde mit einem entsprechenden Wanderdeckelaggregat.The invention relates to a flat set for a revolving flat card, on a flat bar with a corresponding set and on a card with a corresponding revolving flat unit.

Stand der TechnikState of the art

Die Grundprinzipien der Garnierung der Karde sind im "Handbuch der textilen Fertigung, Band 2; Putzerei und Karderie" (Autor: W. Klein, Verleger: The Textile Institute) aufgeführt - siehe insbesondere Seite 52 bezüglich der Verwendung von flexiblen und halbstarren Garnituren auf Deckeln. Die Bedeutung der Garnituren für die Kardierwirkung ist im Artikel ,,Entwicklungen auf dem Gebiet der Kardengarniturkonstruktion" in der Zeitschrift "textil praxis international", September 1994, Seite 551 bis 560 bestätigt worden.The basic principles of garnishing the card are set out in the "Handbook of Textile Fabrication, Volume 2: Blowmaking and Carding" (author: W. Klein, publisher: The Textile Institute) - see in particular page 52 for the use of flexible and semi-rigid covers on lids , The importance of the trimmings for the carding effect has been confirmed in the article "Developments in the field of card clothing design" in the journal "textile practice international", September 1994, pages 551 to 560.

Die Patentliteratur enthält viele Vorschläge für die Herstellung von Deckelstäben mit Garnituren, zusammengesetzt aus Sägezahnstreifen - siehe z.B. EP-A-638672. Die bevorzugte Deckelgarnitur ist aber nach wie vor die flexible oder halbstarre Garnitur, wie Klein sie beschrieben hat. Diese Garniturart hat aber den Nachteil, dass ein (mit Spitzen gespickter) Garniturstreifen (die sogenannte "Basis", normalerweise aus miteinander verklebten Gewebelagen gebildet) an dem Deckelstab durch sogenannte Clips befestigt werden muss. Daher, obwohl die Trägerfläche des Deckelstabes eine Breite von ca. 32 bis 35 mm aufweist, verbleibt für Spitzen nur eine effektive Arbeitsbreite von ca. 22 mm (siehe Klein, "Putzerei und Karderie", Seite 48). Solche Befestigungsmittel sind z.B. in CH-B-521 454, US-B-5,095,585, US-B-4,295,248 und US-B-3,151,362, 3,057,020, gezeigt. Durch die Verwendung der Clipsvorrichtungen gehen die an den Längskanten angrenzenden Randzonen des Streifens als Nutzfläche verloren. Ein weiteres Mittel zum Befestigen von Kardiergarnituren zeigt die DE-A-2544517. Darin werden Kardiergarnituren durch eine lösbar haftende Zwischenschicht an Deckelkörper befestigt. Diese Befestigungsart hat sich in der Praxis aber nicht durchgesetzt.
Es ist die Aufgabe dieser Erfindung hier Abhilfe zu schaffen.
The patent literature contains many proposals for the production of flat bars with trimmings composed of sawtooth strips - see eg EP-A-638672. However, the preferred flat set is still the flexible or semi-rigid set, as Klein has described. However, this type of clothing has the disadvantage that one (spiked with lace) clothing strip (the so-called "base", usually formed from bonded together fabric layers) must be attached to the flat bar by so-called clips. Therefore, although the support surface of the flat rod has a width of about 32 to 35 mm, for tips only an effective working width of about 22 mm remains (see Klein, "cleaning and Karderie", page 48). Such fasteners are shown, for example, in CH-B-521,454, US-B-5,095,585, US-B-4,295,248 and US-B-3,151,362, 3,057,020. By using the clip devices, the edge zones of the strip adjoining the longitudinal edges are lost as useful area. Another means for securing carded sets shows the DE-A-2544517. In it carding sets are attached by a releasably adherent intermediate layer of lid body. This type of fastening has not prevailed in practice.
It is the object of this invention to remedy this situation.

Die Erfindung sieht einen Deckelstab mit einer flexiblen bzw. einer halbstarren Garnitur vor. Einfachheitshalber wird nachfolgend nur von "flexiblen" Garnituren gesprochen, wobei dieser Begriff die "halbstarren Garnituren" ebenfalls umfasst.The invention provides a flat bar with a flexible or a semi-rigid garnish. For the sake of simplicity, only "flexible" trimmings are referred to below, this term also encompassing the "semi-rigid trimmings".

Ein Deckelstab nach der Erfindung ist durch die Merkmale des Anspruchs gekennzeichnet.A flat bar according to the invention is characterized by the features of the claim.

Die Erfindung wird nachfolgend anhand der in den Figuren dargestellten Ausführungsbeispiele näher erläutert. Es zeigt:

  • Fig. 1 bis 4 sind Kopien der Figuren 8 bis 11 aus EP-A-627507 und sie zeigen im schematischen Querschnitt ein Profil zur Verwendung in einem Deckelstab nach der Erfindung,
  • Fig. 5 bis 6 entsprechende schematische Darstellungen von den einschlägigen Teilen von Alternativbeispielen.
The invention will be explained in more detail with reference to the embodiments illustrated in FIGS. It shows:
  • Figures 1 to 4 are copies of Figures 8 to 11 of EP-A-627507 and show in schematic cross section a profile for use in a flat bar according to the invention,
  • Fig. 5 to 6 corresponding schematic representations of the relevant parts of alternative examples.

Das Profil nach den Figuren 1 bis 4 umfasst einen Rückenteil 32 und einen Garnituraufnahmeteil (eine "Fusspartie" 33). Die Fusspartie umfasst zwei Vorsprünge 34 mit schräg nach innen verlaufenden Halteflächen 35. An den äusseren Enden des Deckelstabes 31 sind Kopfstücke 36 befestigt, von welchen in den Figuren nur eines sichtbar ist. Über diese Kopfstücke wird jeder Deckelstab mit einem Ketten- oder Riemenantrieb im Wanderdeckelaggregat (nicht gezeigt) verbunden, z.B. nach EP-A-627507. Da die Verbindung mit dem Antrieb für diese Erfindung keine Rolle spielt, wird sie hier nicht näher erläutert. Die Figuren 1 bis 4 enthalten auch weitere Einzelheiten über die Verbindung zwischen dem Profil und seinen Kopfstücken, die aber ebenfalls für diese Erfindung keine Rolle spielen und deshalb auch nicht näher beschrieben werden.The profile of Figures 1 to 4 comprises a back portion 32 and a garniture receiving portion (a "foot portion" 33). The foot section comprises two projections 34 with obliquely inwardly extending retaining surfaces 35. At the outer ends of the flat rod 31, head pieces 36 are secured, of which only one is visible in the figures. Via these headers, each flat bar is connected to a chain or belt drive in the traveling deck unit (not shown), e.g. according to EP-A-627507. Since the connection with the drive for this invention does not matter, it will not be explained here. Figures 1 to 4 also contain more details about the connection between the profile and its headers, but also play no role in this invention and therefore are not described in detail.

Vorzugsweise, wie in den Figuren gezeigt, wird das Profil als Hohlprofil gebildet. Das Profil kann, z.B. nach US-B-4827573, aus Stahl gezogen, oder z.B. aus Aluminium durch Strangziehen gebildet werden. Der Garniturträger nach dieser Erfindung könnte aber z.B. aus faserverstärktem Kunststoff, z.B. nach DE-A-2742420, hergestellt werden.Preferably, as shown in the figures, the profile is formed as a hollow profile. The profile can, for example, according to US-B-4827573, drawn from steel, or for example made of aluminum by pultrusion. The clothing carrier according to this invention, however, could be made, for example, from fiber-reinforced plastic, for example according to DE-A-2742420.

Die Fig. 5 zeigt eine weitere Variante mit einer "Stahlbandsohle" 66 woran die Basis 50 durch irgendeines geeignetes Mittel (z.B. durch Klebstoff) befestigt ist. Die Sohle 66 kann dann zwischen sich nach innen öffnenden Führungsnuten 67,68 in der Fusspartie 33 des Profils eingeführt werden, wodurch die Basis am Profil befestigt wird.Fig. 5 shows a further variant with a "steel belt base" 66 to which the base 50 is attached by any suitable means (e.g., by adhesive). The sole 66 may then be inserted between inwardly opening guide grooves 67, 68 in the leg portion 33 of the tread, thereby securing the base to the tread.

Die Variante nach Fig. 6 ist im Prinzip derjenigen nach Fig. 5 sehr ähnlich, wobei die Sohle 66A mit schrägen Seitenwände 69 versehen ist, die mit entsprechend angewinkelten Seiten 70 des Profils zusammenarbeiten. Die Basis 50 in dieser Variante besteht aus einem gummiartigen Körper, worin die Spitzen S eingebettet sind.The variant of Fig. 6 is in principle very similar to that of Fig. 5, the sole 66A being provided with oblique side walls 69 cooperating with correspondingly angled sides 70 of the profile. The base 50 in this variant consists of a rubber-like body in which the tips S are embedded.

Weitere Varianten können aus den dargestellten Beispielen abgeleitet werden.Further variants can be derived from the illustrated examples.

Die Garniturstreifen können aus Teilstücken mit z.B. 50 cm Länge auf dem Deckelprofil zusammengesetzt werden.The clothing strips may be made of sections with e.g. 50 cm in length on the cover profile.
