Abstract
Apparatus for making separator envelopes for electrical battery plates having a device for folding an ultrasonically weldable polymeric web around individual battery plates and a device for feeding filled separator envelopes to ultrasonic welding devices, The feed device being provided with two endless synchronously driven feed belts (4, 8) above and below a horizontal feed plane (H) for the separator envelopes (S) as well as symmetrically relative to a longitudinal center plane of the apparatus, which feed belts, with their loops extending parallel to the feed plane, together engage lateral portions of the separator envelopes and which continuously pull the superposed lateral margins of the separator envelopes protruding beyond the feed belts through the ultrasonic welding device.
Claims10
An apparatus for making separator envelopes for electrical battery plates, comprising:
- machine frame means comprising substantially planar feed path means having an input end and an output end;
- ultrasonic welding means positioned on said feed path means intermediate said input and output ends for ultrasonically welding to each other superposed opposite margins of polymeric web means individually folded over a plurality of battery plates;
- means for continuously feeding said folded web means with said battery plates therebetween along said feed path with said opposite margins aligned in parallel therewith through said ultrasonic welding means, said feeding means comprising:
- first and second pairs of endless belt means extending between said input and output ends and positioned in parallel to each other on opposite sides of said feed path, one of said belt means of each of said first and second pairs being positioned above and the other of said belt means of said first and second pairs being positioned below said feed path;
- means for aligning said first and second pairs of endless belt means with said opposite margins of folded web means;
- and
- means for driving said endless belt means in synchronism.
