DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The invention relates to a small textile-finishing installation for treating continuous strips of textile fabric.
Such a small textile-finishing installation is disclosed in DE 14 60 390 A 1. Here, the wet treatment device consists of a trough arranged in a fixed position between feed rolls, in which several guide rollers rotate in the treatment fluid. The textile strip is necessarily brought through the treatment fluid at each turn. At the exit in each instance, a squeezer unit is arranged, from which the textile strip reaches the take-up roll in each instance.
Present-day requirements for a textile-finishing operation are characterized by the short length of the individual yardages, which furthermore consist of changing materials and are supposed to be exposed to different treatments. There is a need to be able to handle these relatively short yardages in an adaptable manner, with the lowest possible expenditure and effort for apparatus, while still providing high quality with regard to uniformity and efficacy of treatment.
SUMMARY OF THE INVENTION
The present invention is directed towards the task of increasing the number and adaptability of the treatments which can be carried out with a textile-finishing installation of the foregoing general type.
The installation for treating continuous strips of textile fabric, comprising a steam-tight housing having an interior and closeable, steam-sealable openings on the housing leading into the interior of the housing. The housing has a vertical plane of symmetry dividing the housing into two equal halves. Feed rolls are located on feed carriages located at opposite ends in the interior of the housing, said carriages being transportable through the openings of the housing. The feed rolls are provided with drives to enable a textile strip to be wound and unwound from the feed rolls in a reciprocal manner.
The apparatus also includes at least one wet treatment device intermediate the feed rolls through which the textile strip passes. The wet treatment device comprises at least one squeezer unit located so that it is generally centered on the vertical plane of symmetry between the feed rolls. An application unit for simultaneous application of conservative amount of treatment fluid on both sides of the textile strip is arranged on each sides of the squeezer unit. An array of guide rollers having upper guide rollers which lie above lower guide rollers over which a textile strip is guided in vertical loops is provided. The bottom guide rollers can be dipped into the fluid tanks provided for this purpose, one array of such guide rollers being provided on each side of the center vertical plane outside of the application units. At least application units and the fluid tanks can optionally be put out of operation in such a way that the textile strip can pass through them without being acted on by the fluid.
The installation according to the invention is symmetrical with respect to its center, so that the same treatment can be carried out when winding the textile back and forth in a reciprocal manner. All the components of the installation, including the feed rolls, are located in a closed housing, in which a steam atmosphere and, therefore, a uniformly elevated temperature, can be maintained.
The squeezer unit in the center allows squeezing the strip after it passes through the application unit in question. The guide roller array allows it to stay in the steam atmosphere, i.e. allows steaming after the application of a dye fluid or a bleaching fluid.
However, the guide roller array can also function as a component of a washing device, if the bottom guide rollers are dipped into the fluid containers and therefore dipping treatment of the textile strip, with a subsequent reaction time, takes place there.
A textile-finishing installation with a housing with a steam atmosphere, a squeezer unit arranged in the center, and a guide roller array provided on both sides of the latter, is known from the reference MELLIAND especially page 423, FIG. 4.
