The scholars from the House of Shammai continue to add specific cases (or examples) of non-involving tasks that take considerable time. Even though you do not have to be present and actively involved in them, the House of Shammai forbade beginning them too close to Shabbos unless there was enough time for them to be completed.
(See previous post for their reasoning.)
The House of Hillel permitted them, so long as you started the task before Shabbos (nightfall on Friday eve).
The examples given:putting bundles of flax into an oven (apparently to whiten them?), putting wool into dye and setting traps for wild animals (birds, fish and game).
