A continuous motion position controlled in-line linear seamer allows a manufacturer or brewery such as a microbrewery to have high speed can seaming (attachment of lids to full cans of beverage) with a single compact, inexpensive, independent and repositionable seaming machine. The seaming is carried out in-line with production, and is done using a linear can path with no need for a large carousel. The motion is continuous because a variable pitch worm drive is constantly operating, driving cans at different speeds for different portions of the can path, including one portion of the path at which the can may remain motionless while being seamed.

Provided is a seaming device capable of preventing dents, caused by a can guide or a seaming turret pocket, and buckling resulting from the dents during seaming, and capable of improving seaming accuracy, by stabilizing the posture of the can being transferred when the can is supplied from an infeed conveyor. The seaming device (100) includes a can placement unit (110) that places a can (C), a seaming chuck unit (120) provided opposite thereto, and a seaming roll (131) that seams an opening of a can (C) and a lid (F). The can placement unit (110) includes a pressing mechanism (111) that presses a plate (112), on which a can is placed, resiliently upward. The seaming chuck unit (130) and the seaming roll (131) are configured to be capable of moving up and down.

A can seaming apparatus comprising a frame, a can handling assembly and a can seaming assembly. The frame has a bottom end and a top end, an upper mounting plate and a lower mounting member. The can handling assembly has an upper chuck and a lower chuck, the upper and lower chucks configured to releasably retain a can and top therebetween. The can seaming assembly includes a roller frame with a first and second roller, wherein the first and second rollers are directable into contact with the can and top while being retained by the upper and lower chucks. The upper chuck is fixed to an axle that extends through the upper mounting plate, and is rotatably coupled to the upper mounting plate. The axle extends beyond the upper mounting plate and structurally configured to be free from obstruction sufficient to allow a for the operable attachment of a chuck of a power tool. A combination can seaming apparatus and power tool is likewise disclosed, as are methods of operation.

An automatic seam detection machine is disclosed herein, including a conveying device and a seam detection device. The conveying device includes a feeding station, provided with a feed valve. When a sample can is conveyed to the feeding station, the feed valve opens and the sample can arrives at the detecting station of the seam detection device through the feed valve. Since more sample cans can be placed in the conveying device, operators can place batches of sample cans in the conveying device in one time; and the sample cans can be automatically conveyed to the feeding station by the conveying device, then conveyed to the seam detection device for detection automatically by opening the feed valve. Compared with prior arts, this invention can achieve automatic feeding, so as to facilitate the batch detection, with high degree of automation.

The present invention relates to an end panel to be seamed by a double seam to a container body which double seam includes an end hook confined by the container body and a body hook, wherein a panel edge of the end panel forms the end hook and is provided with at least one notch, wherein the panel edge includes at least two adjacent edge parts of which a first edge part has a first radius and a second edge part has a second radius or is a straight edge, and the notch has a width to depth ration of about 10 to 150, and is formed in both adjacent edge parts, to a container body and to a container provided with such end panel.
