Abstract: A regulating unit inserted in an installation for preparing batches of containers of the bottle kind. The unit is interposed between an upstream conveyor and a downstream conveyor and at each of its ends, between two adjacent walls (16), includes a mechanism for centering each conveyor module (9). These mechanism includes arms (25) of the same length forming a pair of compasses between two adjacent walls (16), which pair of compasses has a central articulation secured to the conveying module (9) by a sliding connection located in the mid-plane of the corresponding lane. The walls (16) are connected to one another by a pantograph system (30) and a connecting member, having a link rod (35) extending between the pair of compasses and the pantograph to collaborate with the corresponding support of the conveying module (9) in order to keep it in the mid plane of the corresponding lane.

Abstract: The invention comprises, combined in a U-shaped cradle (5), a wrapping table (11) and a cycler (12), the bars (13) of which are mounted on endless chains (14) in order to revolve all around said table (11). The structure (21) of the table consists of side members (23) which are extended by extensions (22) in the form of retractable arms (32), the ends of which carry rollers (33) for guiding the belt (25) and said structure (21) is secured, by way of appropriate, easily removable means, to at least one of the side walls of the cradle (5) which is in the form of a frame (8) perforated by a window (28). The window (28) has a dimension in the longitudinal direction which is less than the overall length of said table (11), but this dimension is greater than the length of said table (11) following retraction of its end arms (32) so that the belt (25) can be removed and a new belt can be fitted.

Abstract: The installation comprises:—an upstream conveyor (2) which supplies the lines of products, and a downstream conveying system, having, between the two;—a unit (5) for regulating the flow of products and, in each lane of said unit, a conveying module (9) of the endless belt type and sets of mobile fingers (8) for controlling the advancing speed of said products. The endless belt of each conveying module (9) extends as far as the inlet of the downstream conveyor (4), and control means are provided to separately adjust the speed of the sets of fingers (8) so as to ungroup the products in accordance with two separate modes:—an ungrouping mode with selection by regulated flow (SRF) and—an ungrouping mode with selection by adjustable fingers (SAF).

Abstract: The regulating unit is inserted in an installation for preparing batches of containers of the bottle kind. This regulating unit is interposed between an upstream conveyor and a downstream conveyor and at each of its ends, between two adjacent walls (16), comprises means for centring each conveyor module (9). These means consist of arms (25) of the same length forming a pair of compasses between two adjacent walls (16), which pair of compasses has a central articulation secured to said conveying module (9) by means of a sliding connection located in the mid-plane of the corresponding lane. The walls (16) are connected to one another by a pantograph system (30) and a connecting member, consisting of a link rod (35), which extends between the pair of compasses and said pantograph to collaborate with the corresponding support of the conveying module (9) in order to keep it in the mid plane of the corresponding lane.

Abstract: The invention relates to an feeding table, comprising a pair of rollers (13, 14), referred to as pressers, arranged downstream from the cutting system, said pair including a motor-driven roller (13) and at least two driven rollers (14) which are arranged so as to form at least two pressure tracks engaging with the plastic film (6) moving between said pair of rollers (13, 14). Each pressure track includes a driven roller (14), the shaft (23) of which is supported by a mobile frame (19) that is guided on a beam (20), wherein said beam (20) is secured to the general frame (2) and a foolproof system for applying pressure is provided between said beam (20) and said frame (19) in order to restrain said driven roller (14) and hold the latter in tangential contact with the motor-driven roller (13).

Abstract: The plant comprises: —an upstream conveyor (2), —a downstream conveyor (4), —a regulating device (7) comprising a system of retractable stops (13) which are inserted temporarily between two consecutive products in a single column, —and means for adjusting the speed of the different conveyors (2, 4), said plant additionally comprising means for adjusting the width of the passages of said adjusting device (7) in order to adapt the width of these passages to the dimensions of said products, and also comprising means for longitudinally adjusting the space between the consecutive rows of stops (13) which move along with the products.
