A method and system for fabricating an article using a first bonding module having a first bonding module face and a second bonding module having a second bonding module face include supplying a first non-woven fabric to at least one of the first bonding module face and the second bonding module face, and supplying a plurality of elastic strands to a surface of the first non-woven fabric. The method and system further include entrapping a first elastic strand between a first pair of adjacent bonds in a first row in the first non-woven fabric, entrapping a second elastic strand between a second pair of adjacent bonds in the first row, and creating a third pair of adjacent bonds in the first row free of elastic bands therebetween. The third pair of adjacent bonds is located between the first pair of adjacent bonds and the second pair of adjacent bonds.

One or more implementations of a multi-layer film include a first layer non-continuously bonded to a second pigmented layer. The multi-layer film includes an unexpected appearance differing from the appearance of the pigmented layer. In one or more embodiments, the multi-layer film includes a metallic appearance despite the pigmented layer being devoid of metallic pigment. The multi-layer film also includes areas that are visually distinct from areas of the film with the unexpected appearance. The visually-distinct areas comprise areas in which the first layer non-continuously is in intimate contact with the second pigmented layer. The visually-distinct areas have the appearance of the pigmented layer or another appearance. One or more implementations also include methods of making multi-layer films and bags with an unexpected appearance and visually-distinct areas.

The present invention relates to an apparatus for producing a gathered material, wherein the material consists of two material web portions and a thread positioned between the material web portions and the two material web portions are connected to one another at two connecting surfaces, wherein the thread is disposed between the two connecting surfaces such that the thread is connected to the material web portions, wherein the apparatus comprises a sonotrode having a first sealing surface and a counter tool having a second sealing surface, wherein the counter tool is cylindrical with a lateral surface and a cylinder axis and the second sealing surface is disposed on the lateral surface, wherein the sonotrode and the counter tool are disposed with respect to one another in a processing position such that the material web portions and the thread can be guided through a gap formed by the first and the second sealing surface in a feed direction tangential to the lateral surface of the counter tool. To overcome or at least mitigate the described drawbacks, it is proposed according to the invention that the sonotrode comprise a groove which is oriented in feed direction and extends over the entire first sealing surface for receiving the thread.

A head for a horizontal flow wrapper packaging machine for forming a bandolier of product packages. The head includes a rotatable first shaft having a plurality of knife elements each including a blade and first and second upper crimping elements. The head also includes a rotatable second shaft having a plurality of anvil elements. A rotation speed of the second shaft is independent of the rotation speed of the first shaft. Each anvil element includes perforation and cutting surfaces and first and second lower crimping elements. A rotation speed of either the first shaft or second shaft is changed to move either a knife element or an anvil element, respectively, between a perforation position and a cutting position. The first upper and first lower crimping elements and the second upper and second lower crimping elements also mate to crimp the packaging material in either the perforating or cutting positions.

A system and method for controlling the speed of both a continuous web and a bonding apparatus is provided in order to effectuate stronger bonds in the web. The bonding system includes a velocity changing device for increasing and decreasing a velocity of the web in a machine direction, an anvil and a corresponding ultrasonic horn that interact to form ultrasonic bonds on the web, and an anvil actuator configured to control a movement of the anvil. A control system is also included in the bonding system for controlling operation of the anvil actuator the velocity changing device, with the control system programmed to decrease a moving velocity of the web from a feed velocity to a bonding velocity as the web passes between the anvil and the ultrasonic horn and control movement of the anvil to synchronize the movement of the anvil with the moving velocity of the web.

The present invention relates to a device for manufacturing a pouch containing a brewable material accommodated in a wrapping, comprising a pouch manufacturing device adapted to manufacture a pouch containing brewable material, and a sealing station with jaw elements forming opposing sealing surfaces acting on the wrapping from opposite sides for sealing the pouch. The device according to the invention allows a more economical production of a packaging unit comprising a pouch in the wrapping and has a trough-shaped recess in which a helically laid heating conductor is accommodated.

A method of bonding a first web of material to a second web of material to form a composite material is disclosed herein. First, a first web of material and a second web of material moving in a machine direction is provided. The webs of material pass over a first energy application device extending transverse in the cross-machine direction. The first energy application device includes a primary bonding pattern and a secondary bonding pattern. The primary bonding pattern in combination with the secondary bonding pattern extends continuously across the first energy application device in the cross-machine direction. In addition, a second energy application device is provided. The second energy application device is moved in the cross-machine direction, and thereby extending the second energy application device over the first energy application device and operating the first and second energy application devices in combination to bond a composite web.

A method and system for fabricating an article using a first bonding module having a first bonding module face and a second bonding module having a second bonding module face include supplying a first non-woven fabric to at least one of the first bonding module face and the second bonding module face, and supplying a plurality of elastic strands to a surface of the first non-woven fabric. The method and system further include entrapping a first elastic strand between a first pair of adjacent bonds in a first row in the first non-woven fabric, entrapping a second elastic strand between a second pair of adjacent bonds in the first row, and creating a third pair of adjacent bonds in the first row free of elastic bands therebetween.
