Abstract
A dewebbing unit and dip tank used in the treatment of tire cord fabric with a liquid coating containing an agent for increasing the bond between the cords of the fabric and rubber material used in the production of tires. The dip tank has a pair of weirs which the liquid coating is caused to overflow for contact with the tire cord fabric which is directed across the weirs. The dewebbing unit includes a chamber in which fluid, under pressure, is alternately passed through the fabric from opposing sides of the fabric to simultaneously vibrate the fabric and pass air through the pores of the fabric.
Claims16
An apparatus used in the treatment of plain woven tire cord fabric, comprising:
- a. means for contacting tire cord fabric with a liquid coating containing an agent for promoting the bond between cords of the fabric and rubber material used in the production of tires;
- and
- b. means downstream of the fabric contacting means (a) for dewebbing the fabric coated with the liquid coating, said means including:
- I. a chamber sealed from the ambient atmosphere;
- Ii. means for guiding the fabric in a vertical plane through the chamber between opposing sides thereof, thereby forming two compartments separated by said fabric;
- Iii. means for alternately circulating fluid, under pressure, to the compartments
- and for alternately evacuating fluid from the compartments in correlated relation to the circulation of fluid to the compartments.
An apparatus used in the treatment of plain woven tire cord fabric, comprising:
- a. means for contacting tire cord fabric with a liquid coating containing an agent for promoting the bond between cords of the fabric and rubber material used in the production of tires, said means including:
- I. means for guiding the fabric along a horizontal pathway;
- Ii. a supply tank for holding liquid coating, the tank including a pair of parallel weirs which liquid coating is caused to overflow;
- Iii. a catch basin surrounding the supply tank for catching liquid coating overflowing the weirs and recirculating it to the supply tank;
- Iv. means for mounting the supply tank and catch basin for unitary movement;
- and
- b. means downstream of the fabric contacting means (a) for dewebbing the fabric.
