Abstract
A machine for forming padded strips, particularly to be used as perimetric bands in the manufacture of mattresses, comprising a machine (1) for dispensing loose material adapted to dispense a continuous layer (2) of loose material and deposit it on a ribbon (5) that is guided along a horizontal table (3), and means (22,23) for moving the ribbon (5) together with the layer (2) through a needle punch (4) adapted to join the loose material to the ribbon.
Description
- The present invention relates to a machine for forming padded strips, particularly to be used as perimetric bands in the manufacture of mattresses.
- It is known that in the manufacture of mattresses perimetric bands are used to join the top and the bottom faces thereof; these bands are constituted by strips of fabric inside which a layer of padding is applied, said layer being constituted by a material having the consistency of foam rubber and appropriately fixed by means of stitching lines that form a zigzag pattern.
- However, in the manufacture of mattresses there are considerable amounts of waste material due to production scraps; their disposal is a cause of high costs, also because of the synthetic part of the material.
- A principal aim of the present invention is to provide a machine for forming padded strips allowing to recover the waste material produced in the processing of fabrics or similar materials based on natural and synthetic fibers.
- Within the scope of this aim, an object of the present invention is to provide a machine that is structurally simple, highly reliable in operation, and versatile in use, as regards both the dimensions of the component to be produced and the type of material being used.
- This aim and this object are achieved with a machine for forming padded strips, particularly to be used as perimetric bands in the manufacture of mattresses, characterized in that it comprises a machine for dispensing loose material adapted to dispense a continuous layer of loose material and deposit it on a ribbon guided along a horizontal table, and means for moving said ribbon together with said layer through a needle punch adapted to join said loose material to said ribbon.
- Further characteristics and advantages of the present invention will become apparent from the following detailed description of a preferred embodiment thereof, illustrated only by way of non- limitative example in the accompanying drawings, wherein:
- the only figure is a perspective view of a machine for forming a perimetric band for mattresses according to the present invention.
- With reference to the above figure, the machine comprises a dispensing unit 1 that delivers a continuous layer of loose material composed for example of production scraps such as fabric shreds, natural and synthetic textile fibers, and the like. The dispenser can furthermore be structured so as to ravel out larger scraps or fabrics and mix them with other products such as cotton-wool, fabric scraps, wool, and the like.
- The dispenser 1 outputs a
continuous layer 2 of loose material that is conveyed onto the receiving table 3 of aneedle punch 4 and is deposited above a ribbon offabric 5 taken from afeeder spool 6. - On the table 3, the
layer 2 and theribbon 5 are guided by two shoulders 7 and 7a the distance whereof is adjustable according to the required width. - The
needle punch 4 is composed of twoside walls cross-member 10 arranged so as to form a bridge. - Two
respective supports side walls vertical posts 13 and 14. - The opposite ends of a
bar 15 are fixed to theposts 13 and 14, and said bar is centrally provided with a bracket 16 to which an end of a linkage 17 is articulated; said linkage is part of a crank system actuated by agearmotor 18 mounted on thecross-member 10. - The crank system comprises a
disk 19 keyed on the output shaft of thegearmotor 18; the second end of the linkage 17 is articulated eccentrically to said disk. Acam 20 is furthermore fixed to thedisk 19; every time thedisk 19 turns, said cam operates aswitch 21 that controls a motor (not shown in the drawing) for the stepwise advancement of atraction roller 22 that is arranged downstream of theneedle punch 4 and cooperates with an underlying belt 23. - The
bar 15 supports a comb composed ofvertical stitching needles 24 protruding downwardly from thebar 15. - Two L-
shaped elements bar 15 at the sides of thecomb 24 and act as a guide for a presser constituted by astrip 27 provided with holes that are aligned with theneedles 24. - The
strip 27 has, at its opposite ends,brackets 28 and 29 that are shaped like an inverted U, straddle thebar 15, and are guided by the L-shaped elements brackets 28 and 29 are actuated downwards byrespective springs 30 and 31 inserted on stems 32 and 33 that extend upwards from thebar 15 through slots of thebrackets 28 and 29. - At the front, that is to say, upstream of the
strip 27, aroller 34 is provided for compacting thelayer 2 of loose material, and downstream of the traction roller 23 acutting unit 35 is provided for trimming the side edges of the strip (loose material and ribbon) at the output of theneedle punch 4. - The
cutting unit 35 is composed of twocircular blades electric motor 39. Theblades support 40, so that their contact plane is substantially co-planar with respect to the belt 23. - The operation of the machine according to the invention is fully evident from the description that has been given.
- The strip composed of the
layer 2 and of theribbon 5 is compressed by passing under theroller 34 and is then compacted by the stitches formed by theneedles 24 that join thelayer 2 to theribbon 5. - It should be noted that every time the comb of
needles 24 lowers, thetraction roller 22, actuated by thecam 20, stops and then continues as soon as the needles have risen into the position in which they are disengaged from the strip. - The strip thus stitched is trimmed along its longitudinal edges by the
circular blades 37 and 38 to the desired width. - The described machine is susceptible of numerous modifications and variations, all of which are within the scope of the inventive concept.
- In particular, it is possible to cover the strip at the output of the needle punch, or of the cutting unit, with an
additional ribbon 41 taken from anadditional spool 42. By means of anappropriate guide 43, the side borders of theribbon 41 are tucked under the borders of the underlyingribbon 5, so as to obtain a "sandwich" band in which thelayer 2 of loose material is interposed between theribbons embroidering machine 44 that joins theribbon 41 to the underlying layer by forming stitching lines having a zigzag or fret-like pattern. - Where technical features mentioned in any claim are followed by reference signs, those reference signs have been included for the sole purpose of increasing the intelligibility of the claims and accordingly such reference signs do not have any limiting effect on the interpretation of each element identified by way of example by such reference signs.
