Definitions

  • the invention relates to a device for heating by contact a flexible sheet, textile in particular running; it relates more particularly to a device of the kind in question for chain printing by the transfer technique.
  • a device for heating a flexible moving material, such as paper, comprising at least one pair of fixed longitudinal convex heating sectors, arranged opposite to define a passage for the material, and means for guiding the material in movement against said fixed longitudinal heating sectors.
  • This device useful for heating paper on a coating machine for the formation of corrugated cardboard, cannot be used in the chain printing of a web of textile threads, because when the scrolling stops, it must, as before, immediately remove the cable from the contact of the fixed heating sectors.
  • this device completely lacks flexibility. In fact, when the running of the tablecloth is stopped, it is not possible to remove the portion of tablecloth included in contact with the heating drum, so that during restarting, it is necessary to cut the entire portion of tablecloth which was included in contact with said heating drum.
  • the invention overcomes these drawbacks. It is aimed at a device of the kind in question, which is easy to produce, reliable, ensures good contact at all points of the sheet and a homogeneous and constant tension, even in the event of the sheet stopping, without thermal disturbance or move the portion of the tablecloth that has stopped. In addition, this device makes it possible to restart the processing without offset of origin.
  • the device according to the invention consists in using a curved shoe formed of two sectors, one hot, one cold, this shoe having means enabling it to pivot when the scrolling of the tablecloth, to immediately bring the cold sector into contact with the stopped tablecloth in substitution for the hot sector Then conversely, to replace the hot sector (maintained at constant temperature) for the cold sector as soon as the water table is restarted.
  • the member delivering the transfer paper is braked, while the member for receiving the spent transfer paper is controlled.
  • the invention also relates to the warp knitting looms equipped with such a device, and in which the drive and reception members for the transfer paper are actuated in synchronism with the running members of the web of knitting yarns.
  • Figure 1 is a schematic summary representation of a device according to the invention.
  • Figure 2 is a schematic sectional representation of an improved heating cylinder.
  • Figure 3 is a summary representation of a chain transfer printing device according to the invention.
  • the contact heating device designated by the general reference (1) ( Figure 1), comprises a cylinder (2) consisting of two semi-cylindrical longitudinal sectors, respectively a hot sector (3) heated by suitable means , and a cold sector (4).
  • This cylinder (2) is mounted around a shaft (5) arranged along its longitudinal axis.
  • the shaft (5) has at one of its ends a toothed pinion (6) intended to rotate the cylinder (2) by 180 °.
  • the toothed wheel (6) cooperates, via a chain (7) associated with another toothed wheel (8), with a double-acting jack (9).
  • the device also comprises two fittings (10) and (11) formed by fixed stainless steel bars, the axis of which is parallel to the shaft (5).
  • the tablecloth (12) which scrolls from right to left, passes under the first input tie-down (10), then under the second output tie-down (11), so that the arc (13) of the tablecloth embraces the cylinder (2) over 180 °.
  • the reference (14) designates the heated or treated tablecloth which goes to the other work station.
  • a suitable conventional device synchronizes the control of the movement of the jack (9) with the triggering of the advancement or of the stopping of the ply (12).
  • the hot sector (3) is normally stationary in contact with the portion (13) of the traveling web. So all the points of the same width of the sheet (13) are subjected to the same temperature, under the same tension and for the same duration.
  • the jack (9) is actuated to rotate the cylinder (2) by 180 °, and thus immediately bring the cold sector (4) into substitution of the hot sector (3) in contact with the embraced sheet (13) immobilized.
  • FIG. 2 represents a particular embodiment of the heating cylinder according to the invention.
  • the two respectively heating (3) and cold (4) sectors are constituted by two identical semi-cylindrical shells of stainless steel, respectively (20) and (21), having insulating means (22) along their contact generators. and (23) to absorb the expansion caused by the heating of the hot shell (20).
  • These expansion means (22, 23) can be produced in a known manner, in particular by radial V-shaped angles.
  • the upper shell (20), the external surface of which is polished, is associated with electric heating resistors (25, 26) held together by wedges which are not shown. These resistors (25,26) are held in place by another semi-cylindrical, coaxial shell (24), for example made of aluminum.
  • the electrical resistors (25,26) are supplied by connections passing through the axis (5). It is important that during operation, the expansion of the hot shell (20) can be done without disturbing the cold shell (21), thanks to the expansion and insulation elements (22,23).
  • FIG. 3 represents a particular embodiment of the invention in its application to chain printing by transferring a sheet (30) of parallel warp threads in movement.
  • the heating cylinder formed of its two sectors respectively hot (3) and cold (4), is associated with an upright (31) placed on a sole (32) comprising the feed and receiving elements for transfer paper (33) , the outer face (34) of which is intended to come into contact with the ply of wires, at least on the portion (13).
  • the transfer paper (33) is cut from a reel (35) whose axis is parallel to the longitudinal axis (5) of the heating cylinder, placed on two idle rollers, respectively (36) and (37).
  • the unwound paper passes over a deflection roller (38) tangentially associated with a driving roller (39).
  • the paper (33) comes into contact with the ply (12) at the level of the input tie-down (10).
  • the paper (33) and more precisely its face carrying the pattern of dyes (34) is in contact with the sheet (13) which heats up.
  • the printed tablecloth (14) separates from the spent paper (40), which passes over a deflection roller (41), and from there is rewound into (42) on two rolls respectively (43 ) and (44).
  • the roller (44) is powered by the belt (46) driven by the engine (39).
  • the belt (47) essentially aims at slowing down the drive of the support roller (36), and thereby ensuring an appropriate tension on the transfer paper (33).
  • the two-position device according to the invention is characterized by its simplicity, by its efficiency, since as soon as the tablecloth scrolling stops and then when it is restarted, it pivots 180 °, which immediately prevents and then re-establishes contact between the heat source and the water table. It follows that during any stop, the sheet is maintained at all points and for the same duration at the same tension and at the same low temperature without offset of origin, and moreover, the heating pad is maintained independently at constant temperature . In this way, during the restart, there is no fault.
