Abstract: FIELD: packaging. 
     SUBSTANCE: invention relates to devices for closing bottles with caps by superimposing and rotating pre-formed threaded caps. Installation (1) for assembling plastic products including caps (2) made with the possibility of connection to base (6) is essentially characterized by at least partially reciprocal shape relatively to specified cap (2). Specified installation (1) contains at least part of assembly line (3) for specified caps (2) and specified bases (6), which defines assembly path (3a) and assembly plane (3b) containing specified assembly path (3a). Specified installation (1) contains a set of spindles (30) made with the possibility of moving along specified assembly path (3a) by means of device (31) and made with the possibility of gripping one of specified caps (2) and specified bases (6) in a controlled manner. Specified spindles (30) are made with the possibility of placing and pressing one of specified caps (2) to specified bases (6) and specified bases (6) to specified caps (2) located on specified assembly path (3a) in specified assembly plane (3b). Specified installation (1) differs in that it also contains positioning device (7) containing at least first detector (70) and second detector (71), control means (5) containing auxiliary control system (53) made with the possibility of progressive movement and rotation of specified spindles (30) in directions perpendicular to specified assembly path and plane (3a, 3b), and containing third code sensor (54) made with the possibility of registering the orientation of specified spindles (30) relatively to specified assembly path (3a). Specified first detector (70) is made with the possibility of registering specified first orientation (6a) of specified base (6) relatively to specified assembly path (3a), specified second detector (71) is made with the possibility of registering specified second orientation (2a) of specified cap (2) relatively to specified assembly path (3a), and specified control means (5) are made with the possibility of registering specified first orientation (6a) of specified base (6) and specified second orientation (2a) of specified cap (29) by means of specified detectors (70, 71) and controlling specified auxiliary control system (53) to align specified base (6) and specified cap (2). Specified detectors (70, 71) are video cameras made with the possibility of registering first image (60) of specified base (6) and second image (23) of specified cap (2), and specified control means (5) are made with the possibility of comparing specified images (60, 23) with control image (8), specified first image (60) and specified control image (8) define specified first orientation (6a) of specified base (6) relatively to specified assembly path (3a), and specified second image (60) and specified control image (8) define specified second orientation (2a) of specified cap (2) relatively to specified assembly path (3a), and specified control image (8) is an image of specified cap (2) and specified base (6) in the assembly configuration and defines specified first orientation (6a) and specified second orientation (2a) in a plane parallel to specified assembly path and plane (3a, 3b).  
     EFFECT: simplification of the system and, thus, the design of the rotary machine used to connect caps to bases.
