Abstract
An apparatus and a method for welding metallic fibers to form a knitted fabric having a predetermined width, include feeding a composite of metallic fibers to an apparatus for welding the fibers to form a knitted fabric, and separately welding a plurality of partial sections of the composite in a time period, in which the composite is at a standstill, for example through the use of a plurality of welding electrode pairs which are disposed over the width of the composite. A method for filtering exhaust gases and an exhaust-gas treatment component are also provided.
Claims21
An apparatus for welding metallic fibers to form a knitted fabric having a predetermined width, the apparatus comprising:
- a plurality of welding electrode pairs to be distributed over the predetermined width of the knitted fabric to be formed and through which the metallic fibers are to be passed;
- at least one stroke configuration effecting a relative movement of at least one welding electrode of a welding electrode pair;
- at least one welding control feeding a welding current as a function of a contact between a welding electrode pair and the metallic fibers;
- and
- a feed control for moving the knitted fabric, said feed control feeding the knitted fabric as a function of a state of said at least one stroke configuration.
A method for welding metallic fibers to form a knitted fabric having a predetermined width, the method comprising the following steps:
- a) feeding a composite of metallic fibers to an apparatus for welding the fibers to form the knitted fabric;
- and
- b) separately welding a plurality of sections of the composite in a time segment in which the composite is stationary.
