Definitions
- Lap winding device for a textile machine for example a lap-winder, provided with an auxiliary belt.
- the present invention relates to a lap-winding device for machines processing fibre webs, such as a lap- winder .
- a fibre processing system envisages processing of the fibre, usually starting from fibre flocks, to obtain a yarn.
- the system is composed of numerous machines; in particular, the carding machines enable a fibre web to be produced .
- a lap-winder positioned downstream of the carding machines, a plurality of webs are wound and joined together, to form a web, wound on a tube to form a- lap .
- the laps are then sent to the combing machines and the web produced by these starting from the laps is sent to the lap-winders, roving frames and spinning frames, for the formation of webs, reels of roving and yarn respectively.
- the laps are formed, in the devices of the known art, by remaining in contact under pressure with two calenders rotating at high speed.
- the lap formed by winding a soft web, especially near the point of initial contact with the primary calender, tends to form a thickening, caused by the resistance of the web being wound against the surface of the first calender. This phenomenon is known in the field as "thickening".
- the purpose of the present invention is to make a lap-winding device, in particular for a lap-winder, able to overcome or limit the problem of formation of the thickening .
- the attached figures 1 to 8 shows diagrams of a lap-winding system according to the present -invention, according to different embodiments.
- a machine for processing fibre webs or a lap such as a. lap-winder, comprises a lap-winding device 1.
- the device 1 has an input area 2 for the input of a web W, coming from machinery upstream of the device 1, for example from winding and joining equipment of the lap-winder.
- the device 1 comprises an input group 4 for receipt of the incoming web W in an input direction IN and deviation of the direction of advancement, positioned in the entrance area 2.
- the input group 4 comprises an input cylinder 6, generally motorised, and at least one input roller, generally idler, positioned around the input cylinder 6 to engage the web W.
- at least one input roller generally idler
- three input rollers are provided 8a, 8b, 8c, around the input cylinder 6 and act in conjunction with it to drag the web W.
- the input group 4 comprises an alignment roller 12, which the web W passes over before continuing towards a forming area 20 of a lap L.
- the input group 4 comprises a pair of output cylinders 12a, 12b, at least one of which motorised, pressure coupled for the transit of the web W between them.
- the lap L is formed by the web W wound around a tube T perforated on the surface.
- the device 1 comprises, in addition, a pair of calenders, for example motorised, preferably with a fixed rotation axis, for the formation of the lap L.
- a pair of calenders for example motorised, preferably with a fixed rotation axis, for the formation of the lap L.
- the device 1 comprises a primary calender 22, rotating around an axis 22', which with the tube T, when this is resting on the primary calender 22, forms a primary contact axis 22a; the primary calender has a primary diameter Dp; the primary diameter Dp defines a primary cylindrical surface 22b of the primary calender 22.
- the web W, coming out of the alignment roller 12 or from the pair of output cylinders 12a, 12b, is directed towards the primary contact axis 22a.
- the device 1 comprises a secondary calender 24, rotating around an axis 24', which with the tube T, when this is resting on the secondary calender 24, forms a secondary contact axis 24a; the secondary calender has a secondary diameter Ds; the secondary diameter Ds defines a secondary cylindrical surface 24b of the secondary calender 24.
- the primary contact axis 22a is misaligned between the primary calender 22 and the tube T in relation to the alignment roller 12, and, specifically, is rearward of it.
- a primary reference plane I' is defined; the primary reference plane I' intersects the primary contact axis 22a; an initial web plane Wi is also defined, tangent to the alignment roller 12 and passing through the primary contact axis 22a.
- the primary contact axis 22a between the primary calender 22 and the tube T is misaligned in relation to the alignment roller 12 in the sense that the initial web plane Wi is inclined in relation to the primary reference plane I 1 , in other words is not orthogonal to it.
- the primary contact axis 22a between the primary calender 22 and the tube T is rearward of the alignment roller 12 in the sense that the initial web plane Wi forms an acute angle with the primary reference plane I 1 on the side of the tube T, in other words an obtuse angle on the -side of the primary calender 22. That is to say, the initial web plane Wi intersects the tube T.
- the initial web plane Wi forms an angle with the primary reference plane I', of 0° to 89°, for example 45° to 85°, for example 55° to 75°, preferably 60° to 65°.
- such arrangement makes it possible to wind the web onto the tube T or to the lap being formed in a joining area upstream of the primary contact axis 22a. It has been found that such aspect considerably facilitates the formation cycle, significantly limiting the thickening phenomenon, since the web is already wound and joined to the lap when it reaches the area of the primary contact axis 22a, where it encounters strong pressure from the calender.
- the initial web plane Wi forms a negative angle with the primary reference plane .1 1 .
- the initial web plane Wi forms an angle with the primary reference plane I' of -15° to 0°, for example of -5°.
- the forming area 20 is asymmetric, in that the primary diameter Dp of the primary calender 22 is a different length from the secondary diameter Ds of the secondary calender (figures 3, 7 or 8), or the distancing of the web being formed from the calenders is not symmetrical but inclines towards the secondary calender (figure 2) .
- a calender axes plane A 1 is defined as the plane containing the two axes 22', 24' of the two calenders 22, 24;
- a reference plane I' is defined as the plane containing the rotation axis 22' of the primary calender 22 and the axis ⁇ " of the tube T;
- the reference plane I'' is defined as the plane containing the rotation axis 24' of the secondary calender 24 and the axis T' of the tube T;
- the median plane M is defined as the plane bisecting the angle 22'- T'-24'.
- the primary diameter Dp is less than the secondary diameter Ds (figures 3, 7 and 8), and, in particular, the ratio of the primary diameter Dp to the primary calender 22 and the secondary diameter Ds of the secondary calender 24 is 0.1 to 0.4, preferably 0.15 to 0.3, preferably equal to 0.23 or 0.27 (figures 3, 7 and 8).
- the plane of the centres T' 1 is inclined, in the forming area 20, so as to be further from the primary calender 22 in relation to the median plane M. It is believed that the reduction in over pressure in the primary contact area 22a derives from this.
- the plane of the centres T 1 1 forms, with the median plane , an angle of 5° to 20°, preferably 10° to 15°, preferably equal to 12° or 13° or 14° on the side of the secondary calender.
- the device 1 comprises an auxiliary belt 40 which forms a closed circuit and is at least partially wound on the primary calender 22, remaining in contact with the tube T and then with the lap being formed (figures 7 and 8) .
- the device 1 comprises a pair of return rollers 50a, 50b, positioned rearwards of the primary calender 22, on the side opposite the forming area 20.
- the auxiliary belt 40 winds onto the primary calender 22 and onto the two return rollers 50a, 50b, forming the closed circuit.
- the lap- winding device 1 comprises a mobile guide 30, for example rotatable, for example in the form of a plate, which the web W moves on.
- the mobile guide 30 is positioned downstream of the pair of input cylinders 12a, 12b and upstream of the primary calender 22 (figures 7 and 8) .
- the device 1 comprises a fixed guide 60, for example in the form of a plate, positioned between the input cylinder 6 and the pair of output cylinders 12a, 12b.
- the mobile guide 30 is positioned downstream of the alignment roller 12 and upstream of the primary calender 22, which the web moves on (figures 3, 4 and 6) .
- the guide 30 is movable from an active position, in which it guides the web W especially when starting the formation cycle, towards the tube T, and a rest position, in which it is distanced from the primary calender, so as not to interfere with the lap being formed.
- the lap-winding device 1 has the primary contact axis 22a between the primary calender 22 and the tube T rearwards of the alignment roller 12 and the asymmetric forming area 20, as well as the mobile guide 30.
- the device 1 comprises suction means 32, joined to the mobile guide 30, to hold the web W, especially during the initial phase of the formation cycle.
- At least some of the components of the device 1 in contact with the web in the forming area 20 of the lap comprise air current evacuation means.
- the primary calender 22 which is in contact with the web W in the forming area 20, has a surface provided with holes (figure 5), from which the currents of air forming in the forming area of the lap, can escape, to reduce their disturbing effect on the web.
