Embodiment Construction

[0012] The embodiment of the inventive method passes through the following steps successively:

[0013] a. The small piece of celluloid sheet is softened by dipping the flannelette into the softening potion and placing it in the container. The softening potion is formulated according to the weight ratio of 4:1 by acetone and ethanol, and the celluloid sheet is spread on the flannelette surface. Close the container and keep the temperature at 20°C. After 24 hours, take out the celluloid sheet and put it into a closed container for use;

[0014] b. Coat the accordion shell with ethyl ester, take out the celluloid sheet and quickly paste it on the surface of the wooden shell coated with ethyl ester;

[0015] c. For the seams between the celluloid sheets, wipe them with ethyl ester, and then rub them with machine sand to make them smooth;

[0016] d. Filling the celluloid sheet slurry in the seam and rubbing it flat, the sheet slurry is formed by soaking the celluloid sheet in et...

Abstract

The invention relates to an accordion manufacturing technique, in particular to a method for sticking an accordion enwrapping sheet, which is used for sticking a covering enwrapping sheet on a wooden shell of an accordion. The method sequentially comprises the following steps: a, softening small pieces of celluloid sheets, wherein the step comprises: placing a cotton flannel soaked with a softening liquid medicament in a container, spreading out the celluloid sheets on the surface of the cotton flannel, sealing the container, keeping the temperature between 10 and 20 DEG C, and taking out the celluloid sheets after 20 to 24 hours and putting the celluloid sheets into a closed container for standby; b, coating ethyl ester on the wooden shell of the accordion, taking out the celluloid sheets, and quickly sticking the celluloid sheets together on the surface of the wooden shell coated with the ethyl ester; c, steeping the ethyl ester to flatten the seams between the celluloid sheets, and leveling up the seams through mechanical sanding friction; d, filling the celluloid sheet slurry into the seams and flattening the celluloid sheet slurry; and e, finally, coating the ethyl ester on the whole surface and then polishing the surface. The method makes the whole surface flattened and smooth so that a naked eye cannot observe obvious gaps, and improves the surface quality of the accordion.

Description

technical field [0001] The invention relates to the manufacturing technology of the accordion, in particular to a method for pasting the accordion wrapping covering the wrapping on the wooden shell of the accordion. Background technique [0002] In the manufacture of the accordion, in order to obtain a smooth outer surface, it is necessary to paste the covering on the accordion wooden shell. The traditional method of pasting the covering is to soften small pieces of celluloid of the same or different colors and glue them together. Pasted on the surface of the wooden shell, there are always obvious gaps between the celluloid sheets after the collage, which reduces the surface quality of the product. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for pasting accordion pieces with good seam joint quality, smooth pasting and smoothness. [0004] The pasting method of accordion bag sheet of the present inve...
