There is provided a method of manufacturing sachets. The method involves moving a web of semi-rigid material through a cutting station and simultaneously cutting a discrete cut in the web of semi-rigid material while the web of semi-rigid material continues to move through the cutting station. The method also includes sandwiching the web of semi-rigid material between a first flexible web of material and a second web of flexible material such that the first web of flexible material seals the discrete cuts in the semi-rigid web of material and the second web of flexible material forms a continuous elongate reservoir with the web of semi-rigid material. There is also provided an apparatus for cutting a web of material. The apparatus has a cutting roller and at least one cutting element protruding beyond the exterior surface of the roller, wherein the cutting element has a cutting profile that is at least partly a zigzag shape. Another apparatus for cutting a web of material the apparatus has a first cutting element and a second opposing cutting element, each cutting element having a cutting profile that is at least partly a zigzag shape. Each cutting element is associated with a cam and a rail that are arranged such that the first cutting element follows a path and the second cutting element follows a path that mirrors the path of the first cutting element. The paths have adjacent sections and/or intersecting sections in which the cutting elements come together to discretely cut the web of material while leaving the material intact.

A rotary impulse sealer includes a roller having a roller body and a plurality of seal bars extending radially outwardly from the roller and spaced apart around the roller body. At least one of the seal bars has a body and a selectively heatable heating element extending along at least a part of a length of the seal bar body. The roller is rotatable through a pre-heating pressure application region in which the at least one seal bar is adapted to apply pressure to a bond area of the bondable material, followed by a heating region in which the at least one seal bar is adapted to heat the bond area, wherein the at least one seal bar and tensioned belt are configured to sandwich the bondable material directly between the at least one seal bar and tensioned belt during the pre-heating pressure application region and the heating region.
A rotary impulse sealer for forming a series of discrete bonds in a bondable material. The rotary impulse sealer has a roller rotatable about an axis. The roller has a roller body and a plurality of seal bars extending radially outwardly from the roller and spaced apart around the roller body. At least one of the seal bars has a body and a selectively heatable heating element extending along at least a part of a length of the seal bar body. The roller is rotatable through a pre-heating pressure application region in which the at least one seal bar is adapted to apply pressure to a bond area of the bondable material, followed by a heating region in which the at least one seal bar is adapted to heat the bond area, the regions being stationary with respect to the rotation of the roller. A method of forming packages containing fluid or fluent material includes continuously providing at least two sheets of bondable material having a fluid or fluent material therebetween, applying pressure to a transverse bond area of the bondable material to force the fluid or fluent material away from the transverse bond area, and heating the transverse bond area to form a seal.
