Abstract
A process is provided for manufacturing devices that carry an active material. The process involves the continuous deposition of a strip of low-melting alloy in the liquid state on a ribbon of a metal net or a micro-perforated and stretched sheet metal, which surface has been pre-treated, for example by means of deoxidation. The ribbon is preferably prepared for subsequent cutting into individual components with active material. The deposition can occur by immersion into laminar wave or into a constant jet, by spraying of small drops or by liquid dispensation.
Claims10
A process for mass-production of devices (21, 21′, . . . ) carrying at least one active material, comprising the steps of preparing a ribbon (1) of metallic material having holes in a form of a metal net or a perforated metal band, pre-treating the ribbon to eliminate passivated surface layers, and depositing along a lateral edge of the ribbon at least one strip (13) of active material in a form of a low-melting alloy in a melted state, such that an amount of the melted alloy is captured by the holes and adheres the active material in the holes of the lateral edge of the ribbon.
