A belt splicer for splicing butt ends of thermoplastic belts together. The splicer uses a plurality of cranks in conjunction with heavy springs to close and rapidly open jaws holding butt ends of a belt in place against a heating wand for melting and against each other for welding the melted ends together. The rapid opening of the jaw also lowers the wand, which is locked in place by a wand lock during the melting of the butt ends.

A belt splicer includes a pair of decks, each configured to hold a belt end. At least one of the decks is movable along a direction perpendicular to the longitudinal axes of the belt ends to impart a shearing force at the at least partially molten interface between the belt ends. The movement of at least one of the at least partially molten mating edges generally parallel to the interface facilitates formation of an improved joint between the belt ends.

The invention relates to a horizontal transverse sealing station (10a-b), in particular for a horizontal tubular bag machine (12a-b), for producing transverse sealing seams (14a-b) on at least one film tube (18a-b) transported in a continuous, at least essentially horizontal transport direction (16a-b), comprising a transverse sealing station base (20a-b) fixedly connected to a packing machine (22a-b), a transverse sealing unit (24a-b), and at least one sealing jaw pair (28a-b) movably mounted on the transverse sealing unit (24a-b) and formed by two sealing jaws (26a-b), the sealing surfaces (30a-b) of which come closer to each other during a sealing process in a sealing movement (32a-b), which relative to the transverse sealing unit (24a-b) is provided with at least one movement component (34a-b) in the transport direction (16a-b), in order to seal material layers (36a-b) of the film tube (18a-b) between the sealing surfaces (30a-b) by way of heating and/or applying pressure, and to remove again at the end of the sealing process. According to the invention the transverse sealing unit (24a-b) is driveably mounted on the transverse sealing station base (20a-b) in a displacement movement (38a-b) that is at least substantially parallel to the transport direction (16a-b).

A bag forming apparatus includes a pair of opposed sealing bars arranged on opposite sides of a forming plane, a pair of guide arms, each extending from a first arm end through the forming plane to a second arm end and carrying a respective one of the pair of opposed sealing bars, a mounting frame to which the pair of guide arms are movably mounted between the first and second arm ends, and a drive shaft connected to the second arm end of each of the pair of guide arms such that shaft rotation is operable to move the pair of opposed sealing bars into and out of engagement across a web of bag forming material traveling therebetween in the forming plane. The drive shaft can be translatable relative to the mounting frame to adjust a closure gap between the pair of opposed sealing bars.

An integrated system for fusing and sealing of a plurality of tubes is disclosed. The integrated system includes one or more fusing units configured to cut one or more tubes of multiple tubes simultaneously, and fusing the one or more tubes together along their respective cut ends; one or more sealing units configured to seal an end of the tube of the multiple tubes; and a control unit for controlling functions of the one or more fusing units and the one or more sealing units.

A packaging machine comprising a transversal sealing unit (20) of bags, substantially consisting of a plate support (21) which comprises a series of additional supports and kinematic organs for the horizontal and vertical activation of grippers (22, 23), one internal and the other external, for the sealing and cutting of each bag, said machine comprising motors (25, 26), mounted on a fixed support (24), which cause the vertical movement of a main carriage (29) and of a gripper carriage (30) by means respectively of a screw shaft (27) and a screw shaft (28), said main carriage (29) supporting two pairs of horizontal and sliding parallel arms (33, 34), the internal first of which control the horizontal movement of the internal grippers (22) and the second control the horizontal movement of the external grippers (23), while the vertical movement of the grippers to follow the moving bag is achieved by the vertical movement of the main carriage (29).

A cross seal device 100 is provided. The device 100 comprising a cross sealing table X having a cross sealing station (A) and a toggle assembly (B). The cross sealing station (A) comprising a front seal assembly (1) and a rear seal assembly (2) configured to engage and disengage by controlled oscillation of first pair of C shaped actuator levers (6c, 6d) and second pair of C shaped actuator levers (6a, 6b) via sealing drive shaft (5) of toggle assembly B. The cross sealing station (A) performs horizontal reciprocating action for sealing. The cross sealing device 100 further comprising Cross Sealing Up Down control assembly C which controls vertical reciprocating movement of cross sealing table X employing Stripping System D to ensure no PIS (Product in Seal) and improves packaging capacity.

The invention relates to a deep-drawing packaging machine and to a method of operating such a deep-drawing packaging machine, comprising a lifting device for a workstation, wherein a lower tool part connected to a stand and an upper tool part connected to a frame are coupled to each other and driven by a motor such that both tools may at least partially move together towards a film web.
