| 摘要 |
The invention relates to a machine for placing sleeves (M) on products (P), said machine having a line (2) for moving the products and a sleeve placement station (3) with pulling members (32) that are controlled by an actuator (33). The placement station comprises a position sensor (4) downstream for the placement station itself so as to detect the position of a sleeve (Mn-i) placed on a product (Pn-i), which is downstream from a product Pn that is in the process of having a sleeve (Mn) placed thereon. The detection signal (SPn-i) is sent to a central unit (5), which analyzes the signal and compares it to a set position (PCj) so as to generate, in the event of a difference, a control signal (SCn) acting on the actuator (33) controlling the pulling members (32) for placing the next sleeve (Mn). |
