Methods and apparatuses for bonding polymeric parts are disclosed. Specifically, in one embodiment, the polymeric parts are bonded by plastically deforming them against each other while they are below the glass transition temperatures. A method includes: placing a first polymeric part in contact with a second polymeric part; and plastically deforming the first polymeric part and the second polymeric part against each other to bond the first polymeric part to the second polymeric part. Additionally, during the plastic deformation, a temperature of the first polymeric part is less than a glass transition temperature of the first polymeric part and a temperature of the second polymeric part is less than a glass transition temperature of the second polymeric part.

A transfer method for expanding pitches of devices includes: providing a first substrate with micro devices having the pitches being a predetermined value in a first direction and a second direction; transferring the micro devices to a first roller by contacting it with the micro devices, wherein a pitch of contact line portions on the first roller is N times of the predetermined value; transferring the micro devices on the first roller to a second substrate; rotating the second substrate by 90 degrees; transferring the micro devices to a second roller by rolling the second roller to contact the micro devices; and then transferring the micro devices to a third substrate to expand the pitch of the micro devices in both the first and the second directions. The portions in contact with the micro devices all have adhesive layers with different adhesion operation windows.

A labelling unit and a method for labelling containers is provided. Said method provides rapid and reliable switching movements with low noise development and low wear of the mechanical components in that suction bars for suctioning label areas at places where container gaps occur can be actively switched back to an inner position, in which they do not come into contact with a gluing unit, and in that the switching process is triggered with the aid of a stationary toggle lever.

The invention relates to a method for producing a butt-welded joint between tube segments of a tube made of a weldable plastic material using a welding machine and to a welding machine (10), two tube segments each being held by a clamping apparatus (11) of a welding device (21) of the welding machine, welding contact surfaces of tube end cross sections of the tube segments being fused by means of a heating element (22) of the welding device and the welding contact surfaces subsequently being pressed against each other by a handling apparatus (18) of the welding device using a joining pressure to form a butt-welded seam connecting the tube segments to each other in a joining plane, the welding device being controlled by a control device of the welding machine, a data model of a tube system having at least one tube and a plurality of butt-welded joints being stored in the control device of the welding device, the data model comprising at least one object dataset representing the corresponding butt-welded joint and each having attributes, the control device detecting at least one weld parameter of the welding device as another attribute for the corresponding butt-welded joint and adding this weld parameter to the object dataset.
