Canning Equipment and Seaming: Steel cans are the 2nd oldesttype of packagingafter glass and clay bottles. They are still popular today, especially for food but for many other products as well. They have a number of desirable characteristics including:
- Tamper resistant
- 崎岖
- Easy to open
- 便宜
- 消费者和包装员熟悉
- Easy to run at high speeds (Up to 3,000 can per minute)
Originally cans were single seamed. The can lid or “end” was cupped, placed over the straight sided can body and soldered in place. Single seam cans are now rare. Virtually all cans are double seamed. The double seamed can seals by mechanical force with no need for potentially contaminating solder. Double seaming eliminates the time and complexity of soldering or welding body and end. Double seaming allows the use of dissimilar materials such as a plastic body with an aluminum end.
Cans are most frequently made of steel or aluminum but can be made of composite board as well as plastic. They are usually round but many products such as processed meat are packed in non-round cans.
In this whitepaper we will focus on圆形的metal cans withdoubleseamed ends.这些may be 2 or 3片. A 2 piece canhas画的罐子，最常由铝制成。这second piece is the end seamed on after filling.

“ can”一词是指带有卷接缝盖的容器，也称为末端。罐子可以是钢或铝，塑料，板或复合材料。可能是2片，带有身体，一端由一块形成，或者可能是3块，两端接缝。他们可能具有直方面，锥形或形状的轮廓。它们通常是圆形的，但专用机器可以接缝椭圆形，正方形或其他形状。接缝机的速度从每分钟几个罐头运行到几千罐。1个头机通常以最高90厘米高的速度运行，具体取决于罐头和盖子。
罐子输入罐头设备（接缝机）单文件。它们通过凸耳链，星骑或正时螺钉与接缝头同步。
一旦在接缝头下方，盖子在4步过程中机械地“接缝”罐子。一旦密封，只能通过切开接缝，末端或身体来打开罐子。这使得罐子高度防篡改。
这seaming process is:
1– The can end is placed on the can body. Some can seamers do this before the can comes into the seaming station. Others, especially 1 head seamers, Shuttle the end horizontally out of a magazine and onto the can body when it is in the seaming station.
2– It is generally easier to raise the can into the seaming rolls than lower the rolls onto the can. After the can and lid have been indexed under the seaming head it is pushed up against the pressure block. This pushes the body and lid tightly together.
一些接缝器将罐子旋转到接缝卷上。另一种选择是将卷卷成一个较大的旋转头，使罐子保持静止。
3– The first seaming roll is pressed against the end. This causes the edge of the end to roll over the body flange forming a “hook”. At this point, the end and body are loosely joined.
4– The second seaming roll irons the seam flat. This forces a tight seal between body and end. After the second seaming, the can is lowered and indexed out of the seamer.
Can seaming is a proven and inexpensive technology. It provides a rugged and tamper proof container for virtually any product.
罐子是历史上最古老，最可靠，通用和具有成本效益的套餐之一。最初，罐头盖或“末端”被焊接到罐子上。这个缓慢，不可靠的过程已被双接缝所取代。
双接缝是纯机械2步骤的过程。当末端放在身体上时，它开始。两者都形成嘴唇或法兰。末端法兰具有弹性体密封剂，可在末端和身体之间提供密封。必须使用足够的下压力来压缩此密封
Once in place, a roller forms the body and end flanges into a “hook” (Step 3 in sketch) This locks the two together but does not seal them.
一旦钩子在末端完全形成后，第二个滚筒将熨平熨斗，缝制接缝，形成最终的密封。
大多数罐是由钢或aluminum. In addition to round cans, there are square, rectangular and other shapes. Plastic and composite paper cans are also common. The basic double seaming process is similar regardless of material or shape.
有2种主要的接缝类型。高速超过150cpm左右，接缝器旋转罐子，迫使钩子和熨烫在其上滚动。较低的速度机，最多150厘米高，使用旋转的缝制cl。
这can is timed into the seamer via lug chain, starwheel, timing screw or a combination. Side clamps grip it to prevent spinning. Once in position under the head, an end is slid onto the can.
A spinning chuck contains the hooking and ironing rollers. In some seamers the can is raised into the chuck. In other designs the chuck is lowered onto the can. In either design, the chuck forces the end onto the body to deform the sealant for a good seal. Once the chuck in in place, a cam forces the 1st, hook, roller in. As the chuck spins, it forms the hook. The roller is retracted, and the 2nd, ironing, roller forced in to complete the seam.
这finished seamed can is discharged via conveyor.
