Abstract

The trimmer unit consists of spiral blades (2) mounted on a cylinder (1) which turns anti-clockwise on its axis, and a flat blade (3) mounted on a support (8). The blades are designed to remove any projecting loops or filaments from a layer of fabric (5) passing over an adjustable thrust member (7). The flat blade has elongated slots in it at an angle of 45 deg. to its cutting edge to give improved ventilation, and a coating of a cobalt- or nickel-based alloy, applied by a semi-transferred plasma procedure to give it a hardness of at least 38 HRC.

Description

La présente invention conceme un dispositif pour l'amélioration de la tenue des lames plates de tondeuse pour l'industrie textile et autres industries dérivées.The present invention relates to a device for improving the behavior of flat mower blades for the textile industry and other derivative industries.

Les tondeuses connues comportent : (selon figure 1) des lames hélicoïdales montées sur un cylindre (1) tournant autour de son axe dans le sens antihoraire, une lame en acier trempé (3) montée sur un support (8). Cet ensemble arase les peluches ou les fils qui dépassent du tissu (5) qui circule (suivant la flèche) tendu sur une table d'appui (7), celle-ci étant réglable en hauteur.Known mowers include: (according to Figure 1) helical blades mounted on a cylinder (1) rotating around its axis counterclockwise, a hardened steel blade (3) mounted on a support (8). This assembly level the fluff or the son which protrude from the fabric (5) which circulates (according to the arrow) stretched on a support table (7), the latter being adjustable in height.

Actuellement les tondeuses qui sont utilisées selon ce principe présentent certains problèmes: - limitation de la vitesse de rotation du cylindre (1) car le frottement des lames de cylindre (2) sur la lame (3) provoque un échauffement excessif qui détériore la trempe de la lame: - usure due au frottement des lames (2) du cylindre (1) sur la lame (3) en acier trempé: - colmatage de la zone (9) par les bourres de tissus provenant de la coupe.Currently mowers which are used according to this principle present certain problems: - limitation of the speed of rotation of the cylinder (1) because the friction of the cylinder blades (2) on the blade (3) causes excessive heating which deteriorates the hardening of the blade: - wear due to the friction of the blades (2) of the cylinder (1) on the blade (3) of hardened steel: - clogging of the area (9) by the wads of tissue coming from the cut.

Les améliorations, qui font l'objet du présent dépôt de brevet sont contenues dans les points suivants (figure 2): - dépôt sur l'arête de la lame (3) avant usinage, d'un alliage base Cobalt ou Nickel d'une dureté au moins égale à 38HRC déposé par procédé "Plasma semi transféré" (procédé permettant de déposer ces alliages, sous forme de poudre, en assurant une liaison soudée, tout en en minimisant les déformations du support. Ces alliages assurent une tenue maximum à l'abrasion à haute température; - exécution d'une série de lumières (11) dans la lame (3) sur toute sa longueur, ce qui assurera le refroidissement nécessaire ainsi que l'évacuation des bourres de tissus de la zone (9), les lumières (11) sont de forme oblongue et disposées obliquement selon angle proche de 45" par rapport à l'arête (12). The improvements which are the subject of this patent application are contained in the following points (FIG. 2): - deposit on the edge of the blade (3) before machining, of a Cobalt or Nickel base alloy of a hardness at least equal to 38HRC deposited by the "semi transferred plasma" process (process allowing these alloys to be deposited, in powder form, ensuring a welded bond, while minimizing the deformations of the support. These alloys ensure maximum resistance to abrasion at high temperature; - execution of a series of lights (11) in the blade (3) over its entire length, which will ensure the necessary cooling as well as the evacuation of the flocks of tissue from the area (9), the lights (11) are oblong and arranged obliquely at an angle close to 45 "relative to the edge (12).

Claims (3)

REVENDICATIONS 1. Lame plate de tondeuse pour l'industrie textile et autres industries dérivées destinée à équiper une tondeuse comportant: - des lames hélicoïdales (2) montées sur un cylindre (1) toumant autour de son axe dans le sens antihoraire; - une lame (3) montée sur un support (8) cet ensemble arase les peluches ou fils dépassant du tissu (5) qui circule suivant la flèche, tendu sur une table d'appui réglable en hauteur, caractérisée par le fait qu'elle comporte des lumières (11) sur toute sa longueur pour permettre la ventilation, d'où élimination des calories et élimination des bourres.1. Flat mower blade for the textile industry and other derivative industries intended to equip a mower comprising: - helical blades (2) mounted on a cylinder (1) rotating around its axis counterclockwise; - A blade (3) mounted on a support (8) this assembly level the fluff or son protruding from the fabric (5) which flows according to the arrow, stretched on a support table adjustable in height, characterized in that it has lights (11) over its entire length to allow ventilation, hence elimination of calories and elimination of stuffing. 2. Lame selon la revendication "1" caractérisée par le fait que son arête reçoit, avant usinage, un dépôt (10) d'alliage base Cobalt ou Nickel, d'une dureté au moins égale à 38HRC, déposé par procédé "Plasma semi-transféré". 2. Blade according to claim "1" characterized in that its edge receives, before machining, a deposit (10) of Cobalt or Nickel base alloy, of a hardness at least equal to 38HRC, deposited by the "Plasma semi process" -transferred". 3. Lame selon les revendications "1" ou "2" caractérisée par le fait que les lumières (11) sont de forme oblongue et disposées obliquement selon un angle proche de 45" par rapport à l'arête (12). 3. Blade according to claims "1" or "2" characterized in that the lights (11) are oblong in shape and arranged obliquely at an angle close to 45 "relative to the edge (12).
