Problems solved by technology

The current method is complex, using a total of seven processing steps
Moreover, these methods cannot be used to directly mark heat-sensitive substrates or non-planar surfaces, and these methods waste the powder used for marking

Embodiment Construction

[0031] figure 1 Denotes a device that uses electrostatics to apply powder onto an item (eg, onto the surface of the item) and generate an image. The device can be used to form coatings or generate images on a variety of different three-dimensional objects, including those with curved, stepped, angled, or flat surfaces. Examples of such items may include, but are not limited to, confectionery for human consumption, food for animal consumption (e.g. dog bones), or non-edible items (e.g. miniature toy cars) and disposal items (e.g. disposable diaper wrapper).

[0032] Such as figure 1 As shown, the apparatus may include: a holder 21 for securely holding an object 22 to be marked with powder; a powder transfer station 31 adapted to electrostatically transfer powder to the surface of the object; Imaging station 13 for selectively melting powder on the surface of the article; powder removal station 41 for removing the unmelted or unsintered portion of the powder from the surface ...

Abstract

The present invention discloses the production of monochrome or multicolor images on surfaces. The surface is moved to the first workstation, the second workstation and the third workstation. An electrical bias is applied to the surface, and powder is electrostatically transferred onto the surface at a first station. Powder is selectively melted or sintered on the surface at a second station. The unmelted or unsintered portion of the powder is removed from the surface at a third station.

Description

technical field [0001] The present invention relates to apparatus and methods for using powder to produce images on food products, moving webs or sheets and other items, and in particular to marking items, webs or sheets using powder. Background technique [0002] There are times when it is desirable to mark an item, web or sheet with an image. While packaging can include a variety of different information, marking directly on a product or item can provide additional product identification, decoration, advertising or sales information. Since materials in sheet form are often used for packaging or to form products that need to include a variety of information, marking directly on the sheet material can provide additional product identification, decoration, advertising or sales information. Sheet materials are used to convey information and there is also a need for direct marking on such sheets. [0003] Several techniques are known for coating or marking different types of ...
