A reel holder is disclosed. In some embodiments, the reel holder comprises an opening configured to receive and hold a reel having packaging material and a transceiver configured to communicate with a tag in the reel to receive information stored in the tag. A filling machine system is also disclosed. In some embodiments, the filling machine system comprises a reel holder and a reel provided with a tag.

Provided is a double-channel paper feeding mechanism and a sheet medium processing device. The double-channel paper feeding mechanism includes a fixed frame, a movable frame and a connection mechanism. The fixed frame is provided with a first channel plate and a second channel plate. A first portion of the first channel plate and a first portion of the second channel plate form a conveying channel. An opening for inserting the movable frame is formed between second portions of the two channel plates. The movable frame is provided with a third channel plate and a fourth channel plate. When the movable frame is mounted on the fixed frame, the second portion of the first channel plate and the third channel plate are arranged oppositely and form a first input channel in connection with the conveying channel, the second portion of the second channel plate and the fourth channel plate form a second input channel in connection with the conveying channel.

In one example, a printed output inspection unit (300) for a web printing system (100). The inspection unit has a first L-inverter (310) disposed in a first plane (315), and a second L-inverter (320) disposed in a second plane (325) offset from the first plane in a direction orthogonal to the first plane. The inspection unit (300) also has an inspection area (340,350) between the first and second L-inverters to view a side (307,309) of a web substrate (305), the inspection area extending in the direction orthogonal to the first plane.

A tape applicator including a housing and an adjustment mechanism. The housing partially defines a cavity. The adjustment mechanism includes a course and an adjustment plate. The course includes a plurality of positions. The adjustment plate is movable along the course among the plurality of positions. The adjustment plate is held in a selected position of the plurality of positions by the housing based on a size of a tape roll configured to be supported in the cavity.

A flexible layer support structure and a retractable device is disclosed. The flexible layer support structure includes a first thin sheet and a second thin sheet arranged in parallel with each other, as well as and a folding spring group sandwiched between the first thin sheet and the second thin sheet and arranged in parallel. The curved elastic pieces in the folding spring group are smoothly overlapped and connected with the thin sheets, so as to enclose a hollow thin-walled elastic structure that can be overlapped and rolled up, can be automatically straightened and has a flat surface. The retractable device includes a winding shaft, a pressure roller, and a flexible layer support structure installed on the winding shaft. The flexible layer support structure of the present disclosure has the advantages in lightweight, high storage ratio, large unfolded area, simple winding, large load bearing capacity, and less damage.
