Production machine for producing rod-shaped products from an endless strand of a strip adhesively bonded to form a tube
The invention relates to a production machine for producing rod-shaped products from a continuous strand of a continuous strip adhesively bonded to form a tube, comprising a device for applying a glue track to a strip, a format portion, in which the continuous strip into the continuous strand by shaping and adhesive bonding, and a cutting device which cuts the rod-shaped products from the continuous strand at a predetermined length, wherein the device for applying the glue track is formed by a device which applies the glue intermittently to form glue-free portions arranged at regular intervals, and a sensor apparatus is provided, which is directed towards the continuous strip or the continuous strand and generates a signal depending on the passage of a glue-free portion, and the device for applying the glue track is designed to change the length of the glue-free portions in the longitudinal direction of the glue track.
Method and apparatus for shaping a continuous web material into a rod
The method for shaping a continuous web material (1) into a rod comprises providing a continuous web material (1) having a glass transition temperature below 150 degree Celsius and gathering the continuous web material (1) from a flat shape into a rod-shape by means of a shaping device (2). The method further comprises providing a cooling means (34) providing a temperature below four degree Celsius, cooling a material contact surface of the shaping device (2) to a surface temperature below four degree Celsius, and cooling the continuous gathered web material by the cooled material contact surface in contact with the continuous gathered web material. Also provided is an apparatus for shaping a continuous web material (1).

Machine and method for making a continuous tubular element with filling having a spacer and/or filter function
A machine for making a continuous tubular element with filling from web material, including first and second means for feeding respective continuous webs, a forming station configured to perform a folding and/or deformation of a first continuous web in a shaped configuration, and a wrapping station wherein the second continuous web is wound in a tubular shape around the first continuous shaped web to obtain the continuous tubular element. Upstream of the wrapping station there is a first gluing device configured to apply at least one longitudinal line of glue on at least one of the continuous webs in such a way as to define at least one gluing zone, said longitudinal line of glue being positioned in such a way as to coincide with a zone of superposing and contact between the two continuous webs feeding out of the wrapping station.
