摘要:
Packages of a rolled photosensitive material comprise a core and a photosensitive material wound around the core, and one package further comprises a light-shielding leader connected with an end of the photosensitive material to shield the circumferential surface of the photosensitive material from light and a pair of light-shielding covers adhered to both sides of the leader in a peelable state to shield the side surfaces of the photosensitive material. Another package further comprises a light-shielding leader connected with an end of the strip material to shield the circumferential surface of the photosensitive material from light and a pair of side light-shielding covers adhered to shield both sides of the rolled photosensitive material so that the joining end substantially conforms to a boundary between the circumferential surface and the side surface of the photosensitive material, wherein at least one of the light-shielding leader and the side light-shielding cover is made of a tearable material in the boundary direction.

A packaging apparatus for packaging rolled articles. The apparatus forms a pair of packaging materials for wrapping side portions of the rolled article. Edges of the pair of packaging materials are adhered to additional packaging material which wraps a circumferential portion of the rolled article. A splicer splices a trailing end of the second packaging material to a leading end of the rolled article and a winder winds the leading end of the rolled article and the second packaging material around the periphery of the rolled article. A gusseting device gussets the pair of packaging materials along the sides of the rolled article.

In a method and apparatus for packaging a rolled web, a feed roller is located near each of opposed end faces of the rolled web to be packaged. The axis of rotation of a feed roller is inclined with respect to the radial direction of the roll, which radial direction intersects perpendicularly to the direction along which a wrapping material having side edge parts folded in L-shapes is fed, such that the outer periphery of the axis of rotation, which outer periphery is taken in the radial direction of the roll, is more forward with respect to the direction, along which the wrapping material is fed, than the inner periphery of the axis of rotation. A folding member is located on the side more forward than the feed roller with respect to the direction, along which the wrapping material is fed. The folding member is supported such that the space between the folding member and the opposed end faces of the roll varies periodically. The feed roller rotates to feed the side edge part of the wrapping material while the side edge part is being imparted with tension towards the center of rotation of the roll. A slack portion of the side edge part of the wrapping material, which slack portion occurs on the side forward from the feed roller with respect to the direction, along which the wrapping material is fed, is folded by the folding member at predetermined intervals onto the opposed end faces of the roll.

A method of and apparatus for checking a wrapping state of a wrapped roll having end face covers by detecting the force required to press-fit a bushing into a cylindrical core tube and comparing the detected force with a threshold value which is based on the correlation between the force required to press-fit the bushing into the cylindrical core tube and the state of tucking of the end face covers.
摘要:
A wrapping state of a wrapped roll of a continuous sheet material which is rolled and wrapped with a sheet-like wrapping material is checked by taking an image of the wrapped roll placed in a predetermined position, and processing information on the image of the wrapped roll with respect to the density of the image, thereby detecting data on wrapping state of the wrapped roll, and determining whether the wrapping state of the wrapped roll is satisfactory on the basis of the detected data.

Provided is a tire defect detection method capable of accurately detecting a thinly extending convex defect of a tire surface. Prior to the start of Step S1, two-dimensional images including a slit light image are successively obtained in advance. In Step S1, a slit light image is extracted from data of a plurality of shot two-dimensional images. In Step S2, an eccentricity component which is deviation resulting from eccentricity is eliminated from the extracted slit light image. In Step S3, a feature quantity is calculated based on the light image from which the eccentricity component is eliminated, and in Step S4, a thinly extending convex defect is detected based on the calculated feature quantity.

摘要:
In a microdevice in which a plurality of fluids respectively passing through a separate introduction channel are merged in a merging section in a micro space to mix the fluids and the mixed fluids are discharged from the merging section via a discharge channel, a tip section of each of the introduction channels comprises a tapered contraction section so as to contract a flow of fluid, the introduction channels are disposed so that central axes of the introduction channels do not intersect at one point each other, and the merging section is formed of a space surrounded with edges of the contraction sections of respective introduction channels. Thereby, reacting fluids can be mixed rapidly each other, and contamination of air bubbles into the whole fluid can be suppressed by narrowing a dead space of a discharge channel immediately after the merging section.
