Phase d’essorage : le linge issu du tunnel est essoré à
l’aide d’une PRESSE, le linge est restitué sous forme
d’une GALETTE géante, disposée sur un tapis roulant. L’eau est récupérée et
réintroduite dans les cycles de lavage.

Designed to press laundry batches processed in any type of
batch washer, the SPR-50 PRESS optimizes subsequent drying
and ironing — making them less time-consuming and more efficient. The
PRESS forms a round “CAKE” of laundry with a flat base.
With high-capacity drainage facilities, water is extracted quickly and gently
from all types of linen. The SPR-50 single-stage press is
available in three different positioning options at the batch washer outlet:
in-line, turns to the right, or turns to the left.

The SPR-50 Extraction Press applies hydraulic pressure to
loads exiting any type batch washer. In doing so, it
efficiently presses linen into a round LAUNDRY CAKE.

Ours works because we have the space for the conveyors, a
CAKE BREAKER, and a rail system. After that good PM takes
care of the rest. … The operators are fed sheets that are separated
and easy to grab. Upstream of the Viking we use a CAKE
BREAKER after the press and then into a sling and onto the rail system.

CAKE BREAKERS are much better than dryers! A video showing a
cake breaker was out 6 or 7 months ago. If I find it I will
post it. Sheet cakes were lifted about 10 feet and dropped against two
stationary bars. These bars were at different elevations.
After the bottom bar the sheets fell into a clean delivery sling.

There's a (different sort of) cake breaker here:

"Cake breaker" is also said of devices performing a similar
function in other fields where the French term "tourteau"
probably replaces "galette":
Cake Breaker (Crusher); A machine for breaking up animal
cake such as linseed or cotton cake - the residue from oil
manufacture.
