Abstract

DC60 (10/02/46) This document describes a forming unit (1) for producing sealed packages (2) from tubes (3) of sheet packaging material fed along a feed path (P) containing a liquid food product with evenly spaced patterns. The forming unit (1) consists of a movable clamping path (6, 6') that can rotate in a circular motion along a section of the feed path (P) to grip and seal the tubes (3) of packaging material in evenly spaced cross-sections, and an adjusting device (23) for adjusting the position of the patterns along the clamping path (6, 6'). The adjusting device (23) consists of a movable traction path (25) which is attached to the movable clamping path (6, 6') and releases a tensile force onto the tubes (3) of packaging material and the assembly. The cam assembly (26) controls and activates the movement of the traction path (25) at a predetermined station (27) along path (P), and the cam assembly (26) contains a first interacting path (30) which is fixed and a second interacting path (32) which is mounted on the aforementioned clamp path (6, 6') which is connected to the traction path (25) and acts in conjunction with the first interacting path (30) by moving the aforementioned clamp path (6, 6') along path (P). In addition, the forming unit (1) contains the drive path (55, 56) which can activate The working unit (1) can be selected to move the second (32) interaction path between the working structure, which acts in conjunction with the first (30) interaction path, and the inactive structure, which is released from the first (30) interaction path. Figures 1 and 7 describe the forming unit (1) for producing sealed packages (2) from tubes (3) of sheet packaging material fed along a feed path (P) containing the liquid food product and arranged in evenly spaced patterns. The forming unit (1) consists of a clamping path (6, 6') that can move in a circular motion along a portion of the path (P) to grip and seal the tubes (3) of the sheet packaging material in evenly spaced cross-sections, and an adjusting device (23) for adjusting the position of the patterns. The said clamping mechanism (6, 6') is fitted with a movable traction mechanism (25) which is attached to the said clamping mechanism (6, 6') in such a way that it releases a traction force acting on the said tube (3) of the package material and cam assembly (26) to control and activate the movement of the said traction mechanism (25) at a predetermined station (27) along the path (P). The cam assembly (26) has a first interoperating mechanism (30) which is fixed and a second interoperating mechanism (32) which is mounted on the said clamping mechanism (6, 6') which is connected to the said traction mechanism (25) and acts in conjunction with the interoperating mechanism. The first interaction (30) is actuated by the movement of the aforementioned clamp-like pathway (6, 6') along pathway (P). In addition, the aforementioned formation unit (1) has an actuation pathway (55, 56) which can be selectively activated to move the second interaction pathway (32) between the active configuration acting in conjunction with the first interaction pathway (30) and the inactive configuration which is released from the first interaction pathway (30).
