Abstract:
1. An ink jet recording apparatus for textile printing, comprising: an ink jet recording section of serial printing type including a conveyer for intermittently conveying a fabric to print on the fabric intermittently conveyed in the ink jet recording section; a recording head unit disposed opposite to the conveyer from its upper side, said conveyer, interlocked with an operation of the recording head unit, is adapted to intermittently convey the fabric while the fabric is stuck onto the conveyer; a feed roll for continuously feeding the fabric onto an upstream end of said conveyer, and a dancer roll unit, said feed roll and dancer roll unit being disposed upstream of said ink jet recording section in order from upstream in the traveling direction of the fabric; the dancer roll unit is configured to move up and down in response to the intermittent movement of the fabric to maintain a constant tension on the fabric intermittently conveyed in the ink jet recording section; a controller configured to detect a signal regarding the up and down movement of the dancer roll unit and, in response to the detected signal, the controller adjusting the rotational speed of the feed roll so that the fabric is continuously fed onto the upstream end of the conveyer; and a drying section, and a traction roll for continuously pulling the fabric from a downstream end of said conveyer for unsticking the fabric from the latter, said drying section and traction roll being disposed downstream of said ink jet recording section in order from upstream in the traveling direction of the fabric, wherein the traction roll adapted to continuously convey the fabric at a speed that is an average of speeds at which the fabric is conveyed intermittently by the conveyer, and wherein a position at which the fabric is unstuck from the conveyer is moved to an upstream side and a downstream side in the conveying direction of the fabric in response to the intermittent movement of the fabric.
