Definitions

• the invention is based on an air texturing machine for processing several monofilaments, with a worktop on which elements such as delivery mechanisms, heating pins and the like are arranged.
• the invention also relates to an air texturing machine for processing a plurality of monofilaments with an air texturing unit which has an air texturing nozzle in a housing which is installed in a stationary manner in a machine frame.
• an air texturing machine is known from EP-A 2 028 945.
• the invention is therefore based on the object of further developing an air texturing machine of the type mentioned at the outset in such a way that it is easier to handle and operate with a clear structure.
• the worktop forms a side wall in a machine frame, from which the elements, in particular the delivery mechanisms and the heating pins, point into the interior of the machine frame.
• the object is also achieved in that the air texturing nozzle is arranged displaceably.
• the air texturing machine according to the invention thus has the essential advantage that, due to its construction, the delivery mechanisms and the heating pins as well as the other elements on the worktop are not only clearly visible for the operating personnel at all times, but the arrangement of the working plate also allows air texturing machines with their rear walls to be placed adjacent to each other.
• a space-saving, element-like construction of several air texturing machines according to the invention is possible, and important units can be shared by the respective air texturing machines as required. If the air-texturing machines according to the invention are set up with their rear walls in relation to one another and additional ones are placed directly adjacent to one another, clear operation, maintenance and monitoring of the individual air-texturing machines is still possible.
• the elements on the worktop remain easily accessible and the toothed belt and toothed belt wheels can also be replaced from the operating side of the machine. If one of the air texturing machines according to the invention is to be converted, serviced or switched off to change the spool, the immediately adjacent air texturing machines can continue to be operated. In the production of the most varied of textured yarns, this allows a high degree of flexibility in the operation of the object according to the invention and ensures good use of the machines.
• At least two air texturing machines according to the invention are set up, it is not only possible to line up the machines directly, but the machines can also be arranged in such a way that a front and rear processing position is created without disadvantage.
• the delivery mechanisms have at least two rollers which can be operated at different speeds and which are arranged coaxially. This has the advantage that several delivery units can be arranged on a small surface of the worktop for carrying out different work steps. The clarity of the thread run is improved and individual positions can be more easily surveyed.
• a traversing device means for winding up the textured yarn and a drive are preferably provided on the worktop.
• the traversing device with the overflow rollers and with the running laying rollers can also be operated with one drive for several air texturing machines.
• the air texturing machine according to the invention preferably borders with a surface spanned from the rear by the machine frame to a corresponding surface of a further air texturing machine according to the invention.
• the machine frame has two vertically extending side supports open to the front. This has the advantage that the machine frame is not only stable and torsionally rigid due to the side supports, but the side supports can also be used as a yarn channel. The yarns coming overhead from a creel are protected and always visible to the individual supply plants in a clear manner in the yarn channel.
• three delivery units each with two rollers and a traversing device and a heating pin in each case, are arranged below an air texturing nozzle and at least one further delivery unit is provided above the air texturing nozzle, which supplies the textured yarn to a convection heater and / or the winding means.
• the arrangement has the advantage that the air texturing machine according to the invention can also be made compact in height.
• the yarns from the creel to the air texturing machine can always be guided at a height that allows the yarns to be threaded in by hand and without climbing aid. This is also possible if a large number of delivery plants are necessary for processing the yarns, since a delivery plant according to the invention can replace two delivery plants known from the prior art.
• the delivery mechanism has three separately operable, coaxially arranged rollers.
• the delivery unit is arranged at a distance from a heating element.
• the air texturing nozzle is arranged displaceably in a housing.
• the housing has U-shaped openings in cross section at the edge of an opening. This has the advantage that the air texturing nozzle can be pulled out of the housing for inserting the yarns.
• the experience in which the yarns are not very simple and difficult to insert into the nozzle in a confined space is made considerably easier. If the yarns pass through the air texturing nozzle, they can be pushed back into the work area.
• the individual yarns are placed in the openings which are open at the top and which feed the individual yarns of the air texturing nozzles in a safe and orderly manner at a distance from one another. The distance between the individual yarns corresponds to a straight yarn run from the respective delivery plant.
