Convection heat treating apparatus for thermal treatment of a traveling substrate that maintains the temperature of the treatment gas so as to eliminate formation of streaks in the substrate without overheating the interior walls of the machine. A pivotally mounted flow control means has integrally formed portions to simultaneously control the flow of treatment gas through an application chamber inlet, and adjacent branch opening which allows treatment gas to pass from a distribution chamber to return chamber for reheating and recirculation without passing through the application chamber and onto the fabric web, and a by-pass opening disposed radially outwardly from the branch opening which permits the treatment gas to pass directly to the circulation means without reheating. The flow control means is adapted to vary the opening of at lest one application chamber inlet between closed and open and to maintain the branch opening closed when the application chamber inlet is varied between open and partially opened to an intermediate extent, and to open the branch opening when the inlet is closed from the intermediate extent.

A stretching machine for webs of textile material includes a feeding region of the machine for receiving a web of material in a given travel direction, a driven drawing-in cylinder for engaging the web of material, mutually and adjustably spaced apart chain tracks being pivotable about vertical axes in the feeding region, endless needle chains each being deflected in a respective one of the chain tracks for running into and out of the web of material, a needle engagement device downstream of the drawing-in cylinder in the given travel direction of the web of material for running the web of material onto the needle chains, a support for the drawing-in cylinder being movable in the given travel direction of the web of material, and a device connected to the support for maintaining a constant distance between the drawing-in cylinder and the needle engagement device.
摘要:
The cylinder for guiding a web of textile material comprises at least one hollow space which is partly filled with a liquid heat carrier and can be evacuated. The pressure increase in the hollow space if the temperature is increased is to be limited to values below a multiple of calculated safety even though heat carriers with a steeply rising vapor pressure curve such as water are used. The solution consists in that only a quantity of heat carrier which can be evaporated completely in the volume of the hollow space already before a predetermined vapor pressure is reached, is contained in the hollow space.
摘要:
An apparatus for blowing air at a spread-out length of textile fabric being transported onward can be reduced in its dimensions and at the same time made more favorable from an energy standpoint during operation if the blow-out nozzles are embodied as injector nozzles. The injector nozzles can be flexibly adapted, in terms of their distribution in three dimensions, to the width of the length of fabric.

A chain conveyor of a fabric web stretching machine includes input and output sides of the machine, an endless roller chain having a forward and rearward running parts, chain links, chain bolts absorbing longitudinal chain forces, stretching devices disposed at each of the chain links, a guide rail disposed at the forward running part forming a support for horizontally directed transverse forces to be exerted on the fabric web, chain wheels disposed at the input and output sides of the machine forming transitions between the forward and backward running parts each having teeth engaging in the chain at respective longitudinal ends of the guide rail, a transverse force roller being associated with each of the stretching devices for transferring transverse forces, roller bearings on which the transverse force rollers are supported about a vertical axis coaxial to a respective one of the chain bolts, the transverse force rollers abutting an outer surface of the guide rail facing away from the fabric web, the tooth rim and the teeth thereon of at least one of the chain wheels having a slit formed radially in the peripheral surface thereof perpendicular to the axis thereof, substantially centrally dividing the at least one chain wheel, and a support strip disposed within the forward and backward running parts and extending into the slit, the support strip having a support edge lying along a tangent of the root circle of the at least one chain wheel parallel to an adjacent part of the guide rail.
摘要:
A fluff filtering device within a convection drying and/or setting machine for treating a textile material web includes a device for circulating an air stream through the textile material web, a device for heating the air stream, an active filter screen with a frame of a given thickness disposed substantially horizontally in an operating position upstream of the heating device in the air stream for preventing fluff and other deposites from reaching the heating device, the active filter screen being substantially horizontally removable from the machine for cleaning, the active filter screen being upwardly movable into another position by a distance at least equal to the given thickness, and another screen slideable under the active filter screen into the operating position when the active filter screen is in the other position.

Method of continuously treating planar textile structures by applying thereto a treatment medium in the form of foam, which includes subsequently applying underpressure to the planar textile structures at a magnitude at which the foam is completely destroyed without any appreciable flow through the material of the planar textile structures.
摘要:
The present invention provides a method and apparatus for monitoring the application of dye to a traveling web of textile material. The apparatus includes a color characteristic detecting assembly which is movable between an initial detecting position in which it detects a color characteristic of the textile material web shortly after the web has emerged from a dye liquor bath and a post-drying detecting position in which it detects a color characteristic of the textile material web after the web has been handled in a drying device. The post-drying detection of the textile material web enables the apparatus to detect an out-of-limits color characteristic situation which may not appear or be detectable until after the web has been subjected to the drying process. The color characteristic detecting assembly is connected to a control unit which controls the nip pressure of a pair of nip rollers which remove excess moisture from the textile material web.
