Abstract: A support device includes a base member and a support member extending from the base member to a proximal end including a support receptacle. The support device also includes a coupling member extending along a stem portion to a head portion laterally spaced from the base member and the support member by the stem portion. A coupling receptacle is positioned opposite of the coupling member, and the coupling receptacle is structured to receive a component corresponding in structure to the coupling member. A system is also disclosed which includes two of these support devices which may be coupled to one another and, optionally, a stacking device which may be coupled to one of the support devices.

Abstract: A storage unit for a labelling system may include a carrier configured to receive a reel supporting the label material. A storage unit may include a fault detection system configured to selectively prevent the label material from travelling along the conveying path, the fault detection system including: a sensor configured to detect whether the label material is present in a detection zone of the conveying path; and a clamp assembly downstream of the sensor along the conveying path, the clamp assembly being configured to clamp the label material to prevent the label material from travelling along the conveying path in response to the sensor detecting that the label material is not present in the detection zone.
