Definitions

• the invention relates to a method for avoiding wrinkling in a spread and in loop form by a Hotflue - over two vertically superposed series of rolls, namely an upper and a lower series of rolls, - guided textile fabric web, each series of rolls in a roller table horizontally and parallel to each other arranged guide rollers, preferably with directed into the fabric loops blast nozzles.
• a Hotflue described in DE 33 363 28 C2 comprises an upper series and a lower series of guide rollers which are mounted parallel to each other and horizontally so parallel to each other in a substantially closed Hotflue housing.
• Within the housing are located in the lower area and in the upper area of series of lower and upper Leitwal ⁇ en over which the fabric is to meander in approximately vertical loops meandering.
• Blasdüsen-2n arranged within the housing parallel to the guide rollers Blasdüsen-2n provided with the aid of gaseous treatment agent, in particular hot air to blow on the fabric and in the clamped fabric loops.
• the tuyeres each sit on blow boxes which are connected to a supply system - in short: compressed gas duct or shaft. In general, the treatment agent is circulated through the machine.
• the fabric should run wrinkle free through ' the hotflue. For this reason, the fabric web (in its longitudinal direction) is drawn through the machine (Hotflue) with a longitudinal tension that is appropriate for the stability of the web material. This longitudinal tension is usually sufficient to rotate the guide rollers by friction. Often, however, auxiliary drives are provided for part or all of the guide rollers.
• the guide rolls usually have a self-supporting length of 1 to 3 m. The larger the distance (eg 1 to 3 m) between the lower and upper series of rolls, the greater the content of the individual Hotflue and thus its drying performance or production speed.
• the invention has for its object to provide a Hotflue, which makes it possible even with relevant sensitive fabric, the textile fabric to be transported without creases through the machine.
• the solution according to the invention is described in the characterizing part of patent claim 1. Some further embodiments of the invention are specified in the subclaims.
• the solution according to the invention for the method specified in the introduction is that the mutual distance between the lower and the upper series of rolls is reduced in the case of inclination of the fabric to form wrinkles.
• the distance of the vertically stacked roller series adjustable so that the wishes Production speed and wrinkle prevention at the same time must be taken into account.
• the roll spacing (the loop length) can be increased. The invention thus makes it possible to operate the hotflue optimally, taking into account the quality of the goods on the one hand and the machine performance on the other.
• each stage can be assigned a flap which is opened when a blow box reaches its position (position of the flap) and is kept closed where the blow box is not.
• the invention preferably relates to the stepwise variation of the adjustability of the respective roller table or the distance between the upper and lower roller series, because proved the continuous variant in previous experiments as structurally complex. For practical handling in training with gradually variable distance between the upper and lower roller series, it is advantageous according to another invention, when the respectively to be raised or lowered roll table stops for setting predetermined levels are assigned.
• the attached drawing shows a cross section to the longitudinal direction of the individual guide rollers by a hotflue.
• the two series of rolls 1 and 2 are each stored in a roller table 3 and 4 respectively.
• Each series of rolls is assigned an arrangement of blow boxes 5 and 6 with nozzles 7 and 8.
• the tuyeres 7 and 8 may extend as slots or rows of holes parallel to the individual rollers 9 and 10 respectively and be directed into the space between two rollers.
• the blow boxes 5 and 6 are supplied from a generally designated 11 compressed air shaft each via a (to be activated in the altitude of the respective roller table 4) air passage 12.
• the fabric to be treated 13 runs according to the drawing in the form of loops 14 shown alternately on the upper roller series 1 and the lower roller series 2, so that the nozzles 7 and 8 blow between each two adjacent rollers 9 and 10 in the fabric loops 14 clamped therebetween can.
• the four partial dashed lines positions I to IV are provided relative to the upper series of rolls 1 for the lower series of rolls 2.
• the lowest position is with drawn by solid lines.
• spindle drives can be provided to raise or lower the lower roller table 4 according to the drawing.
• the connection between the compressed air shaft 11 and the respective (movable) blow box 6 in its positions I to IV can take place in each case via a connecting piece 15.
• 15 flaps 16 may be provided on the fittings, which are opened or closed during positioning of the blow box 6.
• Each stage position of the series of rolls 2 may be an optionally disengageable, stop 17, z. B. for the roller table 4, are assigned.
