Film feeding roller for air cushion maker

Abstract

A film-feeding roller is applicable to an air cushion maker and facilitates alignment of a plastic film roll on roll supporters of the air cushion maker, so as to ensure a plastic film to be continuously and straight released from the film roll to be made into an air cushion.

Description

BACKGROUND OF THE INVENTION[0001]1. Technical Field[0002]The present invention relates to air cushion makers, and more particularly, to a film-feeding roller facilitating alignment of a plastic film roll on roll supporters of an air cushion maker, so as to ensure smooth inflating and sealing processes.[0003]2. Description of Related Art[0004]For protecting packed objects from being damaged under accidental impact, buffer or cushion materials are generally used to fill void. As can be seen in FIG. 1, an air-bubble sheet made of plastic films is one of the most poplar cushion materials. A manufacture employs special equipments to produce such air-bubble sheet as a large piece, and a user can later cut or pucker the sheet at will to fill void in a packing case. However, the manufactured air-bubble sheet is space-consuming at transportation and storage due to its characters of being inflated and non-compressible. Thus, such air-bubble sheet is uneconomic and inconvenient in respect of t...

AI Technical Summary

Benefits of technology

[0006]One primary objective of the present invention is to provide a film-feeding roller facilitating alignment of a plastic film on a roll supporter of an air cushion maker, so as to prevent the film from slanting at the beginning and ensure smooth inflating as well sealing processes.

Problems solved by technology

However, the manufactured air-bubble sheet is space-consuming at transportation and storage due to its characters of being inflated and non-compressible.

Thus, such air-bubble sheet is uneconomic and inconvenient in respect of transportation and storage.

Nevertheless, a conventional desk-top air cushion maker typically suffer from slant film in the maker that tends to cause creases on the film and leads to defective inflating and sealing processes.
