## Abstract

Apparatus for applying filling compound or the like to a rotating optical ribbon stack comprising a stationary bearing through which a viscous substance is applied under pressure, a rotatable journal, and a ribbon wiping die secured within the journal through which a light waveguide ribbon stack may be passed.

## Claims

### Claim 1

Apparatus for applying a viscous substance to a group of rotating optical ribbons, comprising:
a stationary bearing having at least one opening through which a viscous substance is supplied under pressure;
a rotatable journal held within the bearing, said journal having means for securing a ribbon wiping die inserted in the journal;
means for rotating the journal; and,
a ribbon wiping die secured within the journal, the wiping die having a plurality of passages therein through each of which a fight waveguide ribbon may be passed.

### Claim 2 (depends on 1)

Apparatus is described in claim 1, wherein the wiping die passages are in parallel relationship with one another and are flared to spread outwardly at opposing terminal ends.
