Abstract
A machine for the continuous finishing of webs of textile or artificial leather material or the like in accordance with a variety of finishing processes, the machine comprising a reversible continuous flow drum having web feed and withdrawal devices, the feed device being associated with direct radiation means, one or more moistening devices and one or more devices for applying additives, and the drum being mounted in a casing in which are provided a ventilation device, at least one steam spraying device and a radiator, the component of the machine being independently controllable and the drive of the drum being adjustable for achieving any desired angle of rotation of the drum.
Claims11
A machine for continuously finishing a web of material comprising the combination of
- a casing, a drum mounted for rotation within the casing,
- web feeding means for introducing the web into the drum, the web traveling continuously through the interior of the drum, web withdrawal means for withdrawing the web from the drum and casing, ventilating means fixed to the casing for removing air from and introducing fresh air to the drum and casing, steam spraying means fixed to the casing for spraying steam into the drum, a heater mounted within the casing and above the drum for directing heat and infrared radiation to the drum,
- the web feeding means further comprising a housing attached to the casing through which the web travels, direct radiation means within the housing for directing infrared radiation onto the web, and moistening means within the housing and following the direct radiation means for moistening the web prior to its introduction into the drum.
In a machine for continuously finishing a web of material comprising the combination of a casing, a drum mounted for rotation within the casing, a web feeding means for introducing the web into the drum, the web traveling continuously through the interior of the drum, ventilating means fixed to the casing for removing air from and introducing fresh air to the drum and casing, steam spraying means fixed to the casing for spraying steam into the drum, a heater mounted within the casing and above the drum for directing heat and infrared radiation into the drum, and web withdrawal means for withdrawing the web from the drum and casing, the improvement comprising:
- the web feeding means comprising a housing through which the web travels, one end of the housing being attached to the drum casing, withdrawal rollers located at an end of the housing opposite that attached to the drum casing for withdrawing at the web from a roll of material, a conveyor belt extending longitudinally through the housing for conveying the web from the withdrawal rollers to the drum casing, direct radiation means mounted within the housing, following the withdrawal rollers, and above the conveyor belt for directing infrared radiation onto the web, and moistening means positioned within the housing and following the direct radiation means for moistening the web prior to its introduction to the drum, the moistening means arranged so as to direct moisture toward the upper and lower side of the moving web.
