Apparatus for producing a rod of aerosol-generating material is disclosed. The apparatus comprises a first feed device adapted to supply a first web of aerosol-generating material to a processing unit, a second feed device adapted to supply a second web of aerosol-generating material, and a web changeover unit arranged to change supply of aerosol-generating material to the processing unit from the first web of aerosol-generating material to the second web of aerosol-generating material. The web changeover unit is configured to position a leading edge of the second web of aerosol-generating material adjacent to a trailing edge of the first web of aerosol-generating material upstream of the processing unit during changeover from the first web of aerosol-generating material to the second web of aerosol-generating material. A method of producing a rod of aerosol-generating material is also disclosed.

The invention relates to a device for changing a reel and for connecting a new material web to the end of an old material web, with a first reel (101) from which the first material web thereof which is wound thereon can be unwound, a transport device (103), particularly a transport roller, by means of which the first material web can be guided in a guiding region at a transport speed, a second reel (121) with which the new material web can be prepared, a drive device for rotatably driving the second reel, a separating device (142) for cutting through the first material web, by means of which the material web can be cut through in the guiding region or upstream of the guiding region in order to produce a trailing end, and a control and/or regulating device for the mutual adjustment of the trailing end and the beginning (125) of the second material web, such that the trailing end and the beginning of the web are at a distance of more than 0 mm from each other and particularly do not overlap. The trailing end and the beginning of the new material web can be connected to each other in the guiding region of the transport device by means of a connection element, and the transport speed of the trailing end and the beginning of the web corresponds to more than 0 meter per minute in the guiding region.

An automatic replacement device of a secondary battery material including reel support parts to support a supply reel; a material support part spaced apart from the reel support part; clamping parts, each including a clamping roller to come into contact with the material when replacing the supply reel, a vacuum suction part to suction the material by vacuum, a clamping frame to rotatably support the clamping roller and the vacuum suction part, and a cutter to cut the material when coming into contact with the material; first drive parts to move the clamping roller toward/away from the material; and second drive parts to move the cutter toward/away from the material, wherein the automatic replacement device cuts the material as the material is suctioned to the vacuum suction part after being adhered to a material wound around a replacement supply reel when the supply reel is replaced.

A web splice for attaching two webs, such as paper webs used in paper converting operations. The web splice comprises a non-linear butt joint. The butt joint forms an acute included angle () with the side edges.

A method for splicing a material associated with an absorbent article, including: transporting the material in a direction of transport with a material wound around an entrance roll and a moving roll of a dancer unit; splicing a subsequent material with a preceding material which is a material being transported, by bonding a leading end portion of the subsequent material with the preceding material; and cutting the preceding material so that the total length of a bonded portion and an stacking portion is larger than a path length of the material from a downstream end of a winding portion of the material that is wound around the entrance roll to an upstream end of another winding portion of the material that is wound around the moving roll positioned at a reference position.
