Abstract
A spreading machine for a roll (21) of cloth comprises a body (10) which moves back and forth on a stand (29). The machine contains a control circuit and is provided with a driving source and wheels (19), a cutter (16) for cutting cloth into fixed lengths, a cloth dispenser (20) which supports a thickly rolled roll of cloth and guides cloth onto the cloth-spreading portion while unrolling cloth, and a cloth-guiding plate (13) which is provided on the front end of the cloth dispenser (20) and is used for removing folds of cloth and guiding the cloth.
Description
- The present invention relates to a spreading machine for a roll of cloth. More particularly it relates to a spreading machine which is used for unrolling a rolled or folded roll of cloth, cutting the cloth into a fixed length while running on a stand for spreading a roll of cloth and piling the cut cloth.
- The conventional spreading machine comprises a guide roll and a drawing out roller, which are provided on the upper front portion of the spreading machine. The cloth sent out from a unrolling roller on a cloth-supporting stand is supported by the guide roll and led to the drawing out roller, which is rotated to supply the cloth onto a cloth-spreading portion. When the guide roll and drawing out roller are used, however, folds or slack are apt to be produced in the cloth due to disorder of rotation of the guide roll and the drawing out roller. Further, the drawing out roller is required to be rotated synchronously with the running of the spreading machine, which makes the mechanism complicated.
- What is desired is a spreading machine which has a simple construction and by which folds on cloth can easily by removed.
- The present invention provides spreading machine for unrolling cloth comprising a spreading machine body provided with wheels running and a driving source, a roll-of-cloth-supporting stand for supporting a thickly rolled cloth and unrolling cloth, and a cutter means for guiding cloth to a cloth-spreading stand and cutting cloth into a fixed length, characterised in that a cloth-guiding plate is provided on the front end portion of the roll-of-cloth-supporting stand.
- The invention will be described further, by way of example, with reference to the accompanying drawings, in which:
- Figure 1 is a perspective side view of a spreading machine;
- Figure 2 is perspective side view of the machine in an operative condition; and
- Figures 3 and 4 are perspective side views of two forms of stands for supporting a roll of cloth.
- The spreading machine illustrated in Figures 1 and 2 comprises a
machine body 10, astand 20 for supporting a roll ofcloth 21, and acutter 16. - The
machine body 10 is provided, in the interior, with a control circuit (not shown) for controlling operations of various elements and a driving source such as a motor (not shown). Thebody 10 haswheels 19 so that thebody 10 can run on a cloth-spreadingstand 29, and over the front lower portion of thebody 10 and the lower portion of thecutter 16 there is a cloth-directingplate 17. - On the upper portion of the spreading
machine body 10 is arranged the clothroll supporting stand 20, on the upper portion of which a cloth unrolling or dispensingroller 11 is provided and on the rear of which a core-receivingportion 28 is provided. On the front portion of the clothroll supporting stand 20, a cloth-guidingplate 13 made of stainless steel and asensors 14 for making selvages uniform are provided. On the lower portion of thestand 20, is provided asensor 18 for unrolling a roll of cloth, which is projected inside thebody 10. Aknob 12 is used for adjusting the rotation speed of theroller 11 for unrolling cloth. - Working of the spreading machine having the above-mentioned construction is explained with reference to Figure 2.
- The
cloth roll 21 to be subjected to unrolling is placed on thestand 20 with its cores lying on the core-receivingportion 28 and is contacted with the cloth-unrollingroller 11. The roll of cloth is gradually unrolled by rotation of the cloth-unrollingroller 11. Theunrolled cloth 23, hanging as a single loop from the cloth-unrollingroller 11, passes to the cloth-guidingplate 13, slides on theplate 13, during which folds in the cloth are removed and selvages of the cloth are made uniform, is sent onto the cloth-directingplate 17 and is spread on the cloth-spreadingstand 29. At this time, thewheels 19 of themachine body 10 are rotated by the driving source to run back and forth on the cloth-spredingstand 29. When the spread cloth moves in a fixed distance, it is cut in a fixed length by thecutter 16. The amount of the cloth to be supplied is detected by thesensor 18 for unrolling a roll of cloth, which controls the rotation of theroller 11 for unrolling cloth and regulates the amount of cloth to be unrolled. Thesensor 14 for making selvages uniform detects width-wise displacement of cloth. When the width-wise displacement of cloth is detected, the position of the cloth is amended, for example by moving the clothroll supporting stand 20 in the lateral direction. - When a roll of cloth is to be unrolled without contacting a thickly rolled
cloth roll 21 with theroller 11 for unrolling cloth, as shown in Figure 3, thecloth 23 is sent to the cloth-guidingplate 13 in such a manner that thecore 22 of the roll of cloth is supported on a core-holding rod 34 provided on the rear end of the clothroll supporting stand 30, and the cloth drawn out of the thickly rolledcloth roll 21 is passed between theroller 11 for unrolling cloth and alap member 35 covering over theroller 11 while thecloth 23 is pressed on to theroller 11 by thelap member 35. Alternatively, as shown in Figure 4, the thickly rolledcloth roll 21 is placed, with free rotation, on therolls 46 of abucket ladder 44 provided on the rear end of the clothroll supporting stand 40. Thecloth 23 drawn out of the thicklyroller cloth roll 21 is passed between theroller 11 for unrolling cloth and alap member 45 covering over theroller 11 and sent to the cloth-guidingplate 13 while the cloth is pressed onto theroller 11 with thelap member 45. In case of the clothroll supporting stand 40 shown in Figure 4, it is not required to get a core through the thickly rolled cloth and, therefore work for rolling cloth around the core can be eliminated. Further even if the core (made of paper, etc.) is broken, working of unrolling cloth can be effected continuously.
