The invention relates to a coil-transporting carriage with adjustable retaining arms and to a method for the reliable handling of metal coils of small external diameter, or of sleeves, on a coiler mandrel. The coil-transporting carriage has a vertically displaceable coil saddle for accommodating a coil or a sleeve, also has two retaining arms for stabilizing the coil or the sleeve, the retaining arms being arranged opposite one another on the coil saddle and being pivotable by means of rotary drives, and additionally has a second drive unit for moving the coil-transporting carriage. For pulling off from a coiler mandrel, the coil saddle is positioned against a coil located on the coiler mandrel and the retaining arms are pivoted onto the coil. For pushing onto a coiler mandrel, first a sleeve is placed on the coil saddle of the coil-transporting carriage and is thereby guided by the retaining arms.

In one example, an elevator for a roll of print media includes rotatable shafts oriented parallel to one another and translatable supports to support a roll of print media. Each support is operatively connected to the shafts such that rotating the shafts in a first direction raises the supports and rotating the shafts in a second direction opposite the first direction lowers the supports.

A reel handling robot for handling reels of web material, includes a movable arm carrying an end effector having a base, a reel picking tool, and a web gripping tool configured for gripping a head portion of a web on an outer surface of the reel.

An image forming system includes: a transport device including a loop member that turns and that includes multiple grip units, the transport device transporting a medium that is gripped by the multiple grip units as the loop member turns; a formation device that forms an image on the medium that is transported by the transport device; and a processor configured to: cause the formation device to start image formation on a medium that is gripped by a specific grip unit of the multiple grip units in an association mode.
