Cream-sandwiching / capping of filled cookies and wafers without fracture
For filled/sandwich cookie and wafer products, the process deposits a cream or filling layer and mates a top biscuit/wafer onto a filled base, applying enough compression to seat the cap and spread filling evenly without cracking the brittle shell. The biscuits are rigid-but-fragile and dimensionally variable; the filling viscosity changes with temperature. The step sits between baking/cooling and wrapping. It is hard for a robot because it requires force-controlled mating to a target compression while sensing the fracture point of a brittle part - a force-blind press shatters the cap, while too light a press yields a loose, mis-seated sandwich. Today this is handled by dedicated high-speed sandwiching machinery or manual lines; the dexterous value is in adaptive force control across product variation. We identified this through our own research; we have not confirmed the specifics with the customer directly. This page is our researched read — a starting point for that conversation.

Is this the actual task and sequence? What are the real tolerances, cycle rate, and reject criteria, and which steps are today's manual bottleneck? Answering these is what turns this from a researched signal into a validated use case.
