A keyboard-type tone plate percussion instrument which is simple in construction and light in weight and capable of easily unifying key-operation feelings and efficiently outputting well-balanced sounds. Percussion units are arranged to respectively correspond to keys and tone plates and each strike a corresponding tone plate when driven by a key depressing operation. A resonance box has resonance chambers corresponding to the tone plates and each having an opening side thereof close to a corresponding tone plate. The tone plates are constructed into a single-stage structure where they are arranged in an order of tone pitch in a direction of array of the keys so that tone plates neighboring in specific tone pitch are arranged adjacent to each other. The percussion units are constructed into a single-stage structure where they are arranged to correspond to array of the tone plates.

A wrapping machine having a pre-stretching device including a first pre-stretching roller and a second pre-stretching roller, which are tractively coupled via power transmission gears. A first deflecting pinch roller has been fitted to be pressed against the first pre-stretching roller to form a first nip for the film web passed between the first deflecting pinch roller and the first pre-stretching roller. A second deflecting pinch roller has been fined to be pressed against the second pre-stretching roller to form a second nip for the film web passed between the second deflecting pinch roller and the second pre-stretching roller. A lever mechanism moves the first pre-stretching roller between an engagement position and a disengagement position, so that the lever mechanism also moves the first deflecting pinch roller apart from the first pre-stretching roller and simultaneously the second deflecting pinch roller apart from the second pre-stretching roller to allow easier thread-in of the film web end.
