Abstract

A glass roving package 200 is provided which has a simple configuration which can prevent shifting and collapse of the glass roving package 200 during transportation of the package, and for which it is easier to package glass rovings 100 and unpack, and the cost of the glass roving package 200 can be reduced. The glass roving package 200 includes groups of glass rovings 100 stacked on top of each other on a base board 20 , the glass rovings 100 in each group being arranged, and a wrapping material wrapped around an outer circumferential portion of the groups of glass rovings 100 . A displacement prevention sheet 10 is interposed between a lower group of glass rovings 100 and an upper group of glass rovings 100 in order to prevent the upper group of glass rovings 100 from being displaced during transportation of the package.

First claim

The invention claimed is:

1. A glass roving package including groups of glass rovings stacked on top of each other on a base board, the glass rovings in each group being arranged, and a wrapping material wrapped around an outer circumferential portion of the groups of glass rovings, wherein
a displacement prevention sheet is interposed between a lower group of glass rovings and an upper group of glass rovings and the displacement prevention sheet comprises a foamed resin sheet which is in contact with bottom surfaces of the glass rovings in the upper group of glass rovings,
wherein each group of glass rovings is bundled using a bundling strap and the wrapping material is wrapped around the bundling strap together with the outer circumferential portion of the groups of glass rovings.

2. A glass roving package including groups of glass rovings stacked on top of each other on a base board, the glass rovings in each group being arranged, and a wrapping material wrapped around an outer circumferential portion of the groups of glass rovings, wherein
a displacement prevention sheet is interposed between a lower group of glass rovings and an upper group of glass rovings and the displacement prevention sheet comprises a foamed resin sheet which is in contact with bottom surfaces of the glass rovings in the upper group of glass rovings, wherein
each glass roving in the groups of glass rovings has a cylindrical shape having a hollow portion, and a plurality of rectangular displacement prevention sheets are provided between the lower group of glass rovings and the upper group of glass rovings while the hollow portions of the glass rovings in the lower group are in communication with the hollow portions of the glass rovings in the upper group, and
wherein each group of glass rovings is bundled using a bundling strap and the wrapping material is wrapped around the bundling strap together with the outer circumferential portion of the groups of glass rovings.

3. The glass roving package of claim 2 , wherein
the displacement prevention sheet is configured so that the area of a region where the glass rovings in each group are in contact with the displacement prevention sheet is 50% or more of the area of the bottom surfaces of the glass rovings.
