A yarn recovery device includes a support structure that can be associated upstream or downstream with a yarn feed device, a yarn entry eye and exit eye rigidly connected to the support structure; a drum rotatably associated with the support structure having a seat to accommodate the yarn operationally located between the entry eye and the exit eye; the drum being switchable between a deactivated configuration, in which the seat is substantially aligned with the entry eye and the exit eye and the path of the yarn is not diverted by the drum, and an activated configuration, in which the seat is misaligned in relation to the entry eye and the exit eye and the path of the yarn is diverted by the drum that winds the yarn round itself.

A creel system includes a plurality of tension controller apparatuses that hold spools of wire. The tension controller apparatuses apply tension to the wire and may be manipulated to fine-tune or control the tension applied to the wire. The creel system may further include a plurality of sensors that measure operation of the creel system as well as the condition of the wire. In such embodiments, the creel system may include a user-interface that provides data to the operator in real time and with which the operator may interact to control operation of the creel system.

A creel system includes a plurality of tension controller apparatuses supporting wire spools, an air pressure control system operatively connected to the tension controller apparatuses, a loose wire detection system configured to detect a loose wire condition upon contact between a sensor bar and one or more wires, and a central control system in communication with the air pressure control system and the loose wire detection system. The central control system ascertains a wire tension of one or more wires based on data from an apparatus sensor and the air pressure control system, and the central control system is configured to actuate the air pressure control system in response to the wire tension to maintain air pressure between upper and lower pressure thresholds. The central control system is configured to generate a loose wire alarm when the loose wire detection system detects the loose wire condition.

A filament winding apparatus includes a bobbin driving unit, a winding device, and a tension applying device. A filament winding method using the filament winding apparatus includes a temporary suspending step of temporarily suspending operation of the winding device in the middle of winding the fed-out fiber portion around the workpiece. In the temporary suspending step, the length of the feeding path is increased by moving the pressing member while causing the pressing member to press against the fed-out fiber portion in a state of continuing to feed out the fed-out fiber portion from the fiber roll portion.
