Definitions
- the invention relates to an upper pliers knife according to the preamble of claim 1 (see e.g. EP-A-0 368 060).
- a pliers unit with a pliers frame, which is a pliers plate carries and in which a feed cylinder is stored and with tongs arms that are connected to the tongs frame are pivotally connected and carry a pair of pliers knives.
- the pliers unit is between a rear and a front end position back and forth. In the the rear end position presses with a fiber deflector provided cotton wool bottom edge of the top pliers knife, of which a fiber beard through a rotating circular comb is combed out against a front edge of the pliers plate.
- the load on the parts that make up the pliers moving back and forth depends on the number of Back and forth movements per unit of time - number of combs - and the mass of the pliers unit.
- the object is achieved with the im characterizing part of claim 1 specified Feature solved.
- the recess or recesses lead to the required reduction in the mass of the plate. Since the However, recesses only between the two longitudinal edges the plate are provided, but not in the area of Longitudinal edges themselves, the plate can still - similar to a T-beam or C-beam - sufficient rigidity have so that they with their with the fiber deflecting cliff provided longitudinal edge the line pressure of the required Can exercise size and uniformity. Moreover, there is the possibility of the recess or recesses so train and arrange that the rigidity of the Plate in the area of its longitudinal center is higher than in the area of their ends. This can be a further improvement the uniformity of the line pressure exerted by the plate be achieved.
- a combing head contains two tear-off cylinders 1 and 2, a round comb shaft 3 and a pliers shaft 4, all in a machine frame, not shown are stored.
- Pliers cranks are located on the pliers shaft 4 5, on which the rear end of a pliers frame 6 is articulated.
- the front end of the tong frame 6 is on Front supports 7 articulated about the axis of the round comb shaft 3 are pivotable.
- the tong frame 6 carries one Lower clamp plate 8.
- An upper clamp knife 9 is of upper clamp arms 10 worn with the pliers frame 6 around an axis 11 are pivotally connected. In operation the tong frame 6 is moved back and forth by the tong shaft 4.
- the upper pliers knife 9, which in FIGS. 2 to 4 shown on its own consists of an elongated Plate, usually made of metal, in particular Stole.
- a recess in Form one formed in the back surface of the plate Longitudinal groove 9.4.
- the longitudinal groove 9.4 extends with constant depth and width of one end of the plate 9 to the other end, so practical over the entire length of the plate.
- the lower edge 9.1 of the plate 9 in operation a sufficiently uniform line pressure on the cotton W can exercise, it may be desirable to move between the provided both longitudinal edges 9.1 and 9.3 of the plate Form the recess so that the plate 9 in the area their longitudinal center has a higher rigidity than in Area of their ends.
- FIGS. 5 to 7 show an elongated one Plate 19 with one between the lower longitudinal edge 19.1 and the upper longitudinal edge 19.3 provided Longitudinal groove 19.4, the one from the longitudinal center to the ends the plate has increasing depth.
- a plate forming an upper knife can also others Have recesses between their longitudinal edges.
- Fig. 8 shows a plate 29 between its longitudinal edges 29.1 and 29.3 two slot-shaped recesses 29.4 and 29.5, which extends from the two ends of the plate each over part of the length of the plate extend.
- the slots 29.4 and 29.5 do not narrow only the mass of the plate 29, but also result in that the rigidity of the plate 29 in the area of its longitudinal center is higher than at the ends in the area of the slots 29.4 and 29.5.
- Fig. 9 shows an upper pliers knife in Form of an elongated plate 39 made of metal, the between their longitudinal edges 39.1 and 39.3 of the two Outgoing short slots 39.4 and 39.5.
- the longitudinal edges 39.1 and 39.3 further recesses in the form of openings 39.6 available.
- the shapes and dimensions of the openings 39.6 and their distribution are chosen so that the rigidity the plate 39 higher in the area of its longitudinal center than in the area of the ends of the plate.
- the filler can be made of a plastic which e.g. foamed into the openings can be.
