Sealing System and Method For Gusseted And Zippered Bags
An ultrasonic sealing tool including an anvil with a sealing surface, a horn with a sealing surface facing the sealing surface of the anvil, the sealing surface of the anvil including a plurality of beads including a first bead having a first height and at least one second bead having a second height, the second height being less than the first height, the ultrasonic sealing tool delivering ultrasonic vibrations via at least one of the anvil and the horn to create a closure seal in a work piece positioned between the anvil and the horn, the closure seal including a first seal created by the first bead and at least one second seal created by the at least one second bead, the first seal having a weld depth greater than a weld depth of the at least one second seal.
Suspension for a sealing jaw and method for calibrating sealing jaws
A sealing jaw assembly for a sealing unit, and in particular an arrangement for suspending a sealing jaw in a socket is disclosed. The arrangement is based on a first and a second spring arrangement wherein the action of the first spring arrangement onto the sealing jaw may be activated and deactivated.
BAG FORMING APPARATUS
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.
ROTATABLE SEALING JAW ASSEMBLY FOR A FORM, FILL AND SEAL MACHINE
A form, fill and seal machine includes a support frame having an L-shaped track with first and second track portions. A sealing jaw assembly includes first and second guides moveable along the track from a first position, wherein the first and second guides are positioned in the first track portion, to a second position, wherein the first and second guides are positioned in the second track portion. The sealing jaw assembly is rotated 90 degrees as the first and second guides are moved from the first position to the second position. A method of converting a form, fill and seal machine from a first configuration to a second configuration is also provided.
Method and apparatus for bundling packages of absorbent articles
A method of bundling primary packages of absorbent articles into secondary packages includes advancing first and second films in a stretched state in a machine direction. At least two primary packages of absorbent articles are advanced in the machine direction between the first and second films. The primary packages are compressed in a first direction, wherein the first direction is orthogonal to the machine direction. The primary packages are advanced in a second direction, wherein the second direction is opposite the machine direction. The first and second films are bonded together to form a bonded region. The first and second films compress the primary packages of absorbent articles in the first direction, forming a secondary package around the primary packages of absorbent articles. The bonded region is cut to form a first bond on a first secondary package and a second bond on a second secondary package.
Method and Apparatus for Packaging a Collective Product, and Such Packaged Product
System, hardware, and methods for agitating a package pre-form containing a charge of product elements thus to provide for product settling in the package pre-form before forming the final transverse seal. The product is caused to settle in the package pre-form by apply a plurality of rapid jerk-type acceleration forces to the packaging material, thus to cause rapid longitudinal and/or lateral acceleration in the packaging material.
Undulating Plastic Film Supporting and Aligning Apparatus
Apparatus for vertically supporting and maintaining a web of plastic film horizontally aligned in applications such as machines that form the plastic film into bags and fill them. Separate coplanar consecutively spaced plates are aligned with and extend through a web normal traversing plane. One of the plates has a peak edge extending out of the web normal traversing plane in a first direction, whereas another has a peak edge extending out of the web normal traversing plane in a second opposite direction. The peak edges define an undulating plastic film travel path between a web upstream location and a web downstream location. The web of film is tensioned between the upstream location and the downstream location and travels along the continuous undulating path. The film flexibly bends over the peak edges as a result of the tension and is thereby supported and maintained aligned.
Vertical packaging machine for food products
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).
System and method for forming and moving an article array
A system for forming and moving an article array including a consolidation area having a support surface for receiving and arranging rows of articles to form an article array from an article row delivery device while the consolidation area continuously stabilizingly supports the periphery of the article rows positioned on the support surface as the article rows are arranged to form the article array.
Cross sealing device
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.
