Definitions
- the object of the present invention is a stretcher for tubular knitwear fabric, especially for application to calenders or other machines for the treatment of tubular fabric.
- stretchers are used during the finishing step of tubular knitwear articles for stretching and spreading the tubular article in order to ease the finishing operations.
- calendering which is usually the last finishing operation, it is necessary to use a stretcher in order to achieve a uniform vaporisation and to adjust the width of the tubular article to the desired value.
- Stretchers are known, such as, for example, the one protected by the European patent No. 0791092 assigned by the same Applicant of the present invention, in which the fabric is pressed between a ring or a shaped wheel and two inclined wheels, and consequently streaks or marks can be produced into the fabric.
- the above embodiment is for keeping the stretcher arms in the right position by means of the pressure said inclined wheels exert against the shaped wheel, with the consequence of a pressure onto the fabric and thus of possibly damaging it.
- This embodiment has the draw-back that said deformable parallelograms not only provide safety in case the magnets should not work properly, but also exert an excessive pressure onto the fabric against the driving wheels, thereby producing marks or streaks onto the fabric. This pressure is always acting, also when the sole attraction force of the magnet would be enough.
- the purpose of the present invention is to obviate these draw-backs, with the advantage that between the stretcher arms there is no pressure member. Only the inclined wheels, which are constantly offset from the shaped wheels that are applied to said arms, because they are attracted by the magnets, might, in an emergency case, press the fabric against the shaped wheel, but only for a short time because upon adjustment of the magnet the inclined wheels are immediately removed from the shaped wheel that goes into contact with the driving wheel.
- Figure 1 shows a front view of the stretcher
- Figure 2 shows an enlarged partial horizontal section view of the stretcher along line II-II of figurer 1 ;
- Figure 3 shows an enlarged view of a portion of the stretcher.
- the subject stretcher is comprised by stanchions 1 and 2 in which the several control and driving mechanisms are contained, that are not visible in the figure.
- Said stanchions support the known vaporiser 3 within which the tubular fabric 4 is caused to slide after passing through the stretcher that is the object of the present invention.
- Said stretcher comprises the stretcher arms 5 and 6 that in turn are supported by the support devices that are described hereinafter.
- stanchions 1 and 2 motor means that are not shown in the figure transmit the motion to the upper driving wheels 7a, so that means that are not shown in the figure can cause the stretcher arms 5 and 6 to be displaced in opposite directions in order to possibly modify the width of the tubular fabric.
- the upper driving wheels 7a are connected to the similar lower wheels 7b through means that are specified hereinbelow.
- the stretcher arms 5 and 6 carry wheels or rings 8 that are suitably shaped, said wheels or rings being arranged in front of the bulging portion the driving wheels 7a and 7b are provided with.
- These in turn have supports 9 that support the wheel pairs 10 and 11 with inclined axis 12.
- Said wheels 10 and 11 with their peripheral parts are spaced apart from the circumferential outlines 8' of rings 8, this being due to the magnetic attraction force that acts onto the arms, as will be explained hereinafter.
- the transportation of the tubular fabric 4 is carried out by means belts 13, said belts being wound around a set of pulleys 14 that are idly supported on the arms 5 and 6 along the contour of the driving wheels 7a and 7b and of the rings 8.
- both of the inclined wheels 10 are driven as they are connected to each other by means of an elastic belt 15 that is wound around the driving wheels 7a and 7b and the idle pulleys 7c.
- the inclined wheels 11 are driven because they are connected by means of elastic belts to the same driving wheels 7a and 7b.
- Said driving has the advantage of markedly improving the transportation of the fabric.
- the supports 9 consist of fork brackets 16 for the adjustment of the working angles of arms 5 and 6.
- the wheels 10 and 11 are kept spaced apart from the rings 8 by means of magnets 17, 18 that attract the arms 5 and 6, respectively, outwards as shown by arrows B.
- Said rings 8 carried by arms 5 and 6 remain offset from the inclined wheels 10 and 11 and attracted against the driving wheels 7a, 7b by said magnets 17 and 18, and the fabric is advanced between the belts 13 and the driving wheels 7a, 7b.
- Said adjustment is obtained by means of a mechanism that causes the magnets 17 and 18 to be moved towards to or away from the arms 5 and 6, respectively.
- the magnets 17 and 18 are connected to said mechanism, which is provided with an adjustment hand grip 19, said hand grip being suited to cause the magnets 17 and 18 to move towards to or away from the supports 17' and 18' that are fixedly connected to the bars 5 and 6.
- the tubular fabric 4 which usually consists of several tubular pieces sewn together, is introduced from below, as can be seen in figures 1 and 2, between the wheels 10 and 11 and the ring 8, and between the ring 8 and the wheels 7a and 7b of each arm, thus being transported upwards in the direction of arrow A as the driving wheels 7a, 7b, that are coupled to the rings 8 and to the pulleys 14, rotate, said pulleys being mounted on the arms 5 and 6 that are kept in the right position and supported by the attraction force of the magnets 17 and 18.
- the stretcher can take all the positions from a minimum distance to a maximum one without the need to change the stretcher and thus without any machine stopping time for slipping the tubular fabric off the stretcher arms.
