Abstract
A gas heated direct fired center tube revolving ironer for use in an automated fabric ironing environment features improved roller surface temperature distribution control. An adjustable hot air recirculation system with a venturi throat, a high momentum gas burner, an improved temperature control system and an exhaust blower cooperate to provide an even temperature along the ironing surface. Multiple high and low temperature controls provide backup and ensure accuracy and safety. The gas fuel consumption is minimized thereby reducing operating costs.
Claims12
A gas heated direct fired center tube revolving ironer and dryer comprising:
- a rectangular frame enclosing a revolving cylinder the outer surface of which provides an ironing surface;
- a tube concentrically supported within the cylinder by a plurality of spaced struts rigidly attached to the tube and cylinder whereby the tube and cylinder revolve together;
- said cylinder being closed at one end and open at the other;
- said tube being open at both ends and terminating short of said closed end of the cylinder to provide a chamber through which said tube communicates with the space between the tube and the cylinder;
- a movable plate mounted by means such that it can be positioned adjacent to the open end of the cylinder;
- and
- said movable plate having a means to be locked into a selected position;
- said plate having a high velocity gas burner mounted in the center thereof allowing the flame to be projected down the center of said tube, and said burner having a full proportional flame temperature controller and a high temperature cut-off for said controller.
A gas heated direct fired center tube revolving ironer and dryer comprising:
- a rectangular frame enclosing a revolving cylinder the outer surface of which provides an ironing surface;
- a tube concentrically supported within the cylinder by a plurality of spaced struts rigidly attached to the tube and cylinder whereby the tube and cylinder revolve together;
- said cylinder being closed at one end and open at the other;
- said tube being open at both ends and terminating short of said closed end of the cylinder to provide a chamber through which said tube communicates with the space between the tube and the cylinder;
- a movable plate mounted by means such that it can be positioned adjacent to the open end of the cylinder;
- and
- said movable plate having a means to be locked into a selected position;
- an ironing surface temperature sensor comprising a thermocouple mounted between rollers which roll on the ironing surface, said thermocouple being mounted in direct contact with a wear surface strip of heat resistant and conductive material which intercedes between the ironing surface and the thermocouple element;
- said plate having a high velocity gas burner mounted in the center thereof allowing the flame to be projected down the center of said tube.

- a movable plate mounted by means such that it can be positioned adjacent to the open end of the cylinder;
- and
- said movable plate having a means to be locked into a selected position;
- said struts being capable of withstanding dimensional changes of the cylinder and center tube cause by heat;
- said plate having a high velocity gas burner mounted in the center thereof allowing the flame to be projected down the center of said tube.
