Automatic unwinder of flexible materials comprising feeding means for feeding the operating machine with at least a flexible material, defining a mouth, susceptible of being traversed in the advancement direction of the material, and at least a slide guide, extended between a first end, in proximity to the mandrels, and a second end, in proximity to the mouth, and a rack, at which portions of flexible materials can be retained. The automatic unwinder further comprises at least a carriage, provided with a retention gripper, and movement means in order to move the carriage along at least a slide guide between a grip position, in which the carriage is at the first end and the gripper is susceptible of grippingly receive a free flap of the flexible material, and a release position, in which the carriage is at the second end to release the free flap at the rack.

A web unwind stand for obtaining, loading, splicing, and unwinding a web material from a plurality of convolutely wound rolls and forwarding the web material unwound from each of the convolutely wound rolls uninterruptedly to a downstream apparatus is disclosed. The unwind stand has a frame, a positionable roll grasping apparatus having a mandrel connectively engaged thereto and, splicing means. The positionable roll grasping apparatus is capable of obtaining and disposing the convolutely wound rolls proximate to the splicing means relative to the frame.

The invention relates to a mobile robot, to a supply system, and to a method for changing label rolls on a labeling assembly for labeling containers. The mobile robot accordingly comprises a vehicle unit for changing locations of the robot and a manipulator unit with a multi-axle manipulator and an associated end effector for manipulating label rolls. Because the end effector is designed to grip the outer circumference of the label rolls and emptied roll cores of label rolls so as to carry them, ergonomically problematic work steps when introducing label rolls can be accomplished exclusively by machine with a high degree of precision and in a material-saving manner.

A tape removal apparatus is configured for automatically removing a tape attached to an electrode roll in order to fix the electrode roll. The tape removal apparatus includes a sensing unit configured to sense the tape attached to the electrode roll, an injection unit configured to inject air toward the tape, a support unit configured to support a non-adhesive portion of the tape, and a gripper configured to fix the non-adhesive portion of the tape together with the support unit.

An automatic replacement apparatus for a feed material includes a discharge unit discharging a feed material to the outside, a pair of feed units disposed to be adjacent to the discharge unit and having a feed roll around which the feed material is wound, and a pair of material joint units respectively provided in the pair of feed units connecting a front end of a first feed material waiting in a first feed unit, one of the pair of feed units, and an end of a second feed material being transferred from a second feed unit, the other of the pair of feed units, to the discharge unit in a butt joint manner.

An apparatus is disclosed for applying tags with attached elastic anchor bands onto the tops of objects such as bottles in a high speed packaging application. The apparatus includes an infeed assembly for feeding a web, a conveyor assembly that receives a web and conveys it along a path in an upstream direction, a rotating selector wheel, a placement assembly, a pair of rotating jaw assembles, a vacuum cup of the selector wheel, and stretched elastic bands over the tops of respective bottles being conveyed along a path below the placing assembly. The elastic bands then snap onto the tops of their respective bottles to secure the tags to the bottles.

An adhesive bonding system joins flat webs when changing rolls of such webs. The adhesive bonding system comprises two adhesive tape boundary edges, and further comprises a top carrier layer and a bottom carrier layer, a flat connecting element that connects the two carrier layers to one another and is suitable for opening the connection under the conditions of a static or flying roll change. At least one of the boundary edges of the connecting element does not extend in a straight line, and a straight-line emphasis line is defined in relation to this boundary edge, the emphasis line of this boundary edge extends along a preferential direction, and this boundary edge has a multiplicity of regions lying on one side of its emphasis line and also a multiplicity of regions lying on the other side of its emphasis line.

An automatic tape processing device includes a feeding device in which a cover tape is adhered to an upper surface side of a base tape in which cavities configured to accommodate a component are provided at a constant pitch, the feeding device being configured to convey a carrier tape to be loaded into a tape feeder, a cutting device configured to cut each of the base tape and the cover tape at a cutting portion, and a control device configured to determine the cutting portion of each of the base tape and the cover tape according to a type of the tape feeder and control operations of the feeding device and the cutting device so that the base tape and the cover tape are cut at the determined cutting portion.
